Squishy Circuits with Play-Doh
Making circuits with Play-doh is pretty cool. If you have some doh at home you can use that for conductive circuits. To take it to the next level you will need some insulating doh as well. Below are recipes for both at home conductive and insulating “Play-doh”.
Making Conductive Play-doh
The Ingredients
- 1 cup Water
- 1 1/2 cups Flour
- 1/4 cup Salt
- 3 Tbsp. Cream of Tartar (or 9Tbsp of lemon juice)
- 1 Tbsp. Vegetable Oil
- Food Coloring (optional)
Cooking Procedure
- Mix water, 1cup of flour, salt, cream of tartar, vegetable oil, and food coloring in a medium sized pot.
- Cook over medium heat and stir continuously.
- The mixture will begin to boil and start to get chunky.
- Keep stirring the mixture until it forms a ball in the center of the pot.
- Once a ball forms, place the ball on a lightly floured surface.
- The ball will be very hot. We suggest flattening it out and letting it cool for a couple minutes before handling.
- Slowly knead the remaining flour into the ball until you’ve reached a desired consistency.
- Store in an airtight container or plastic bag. While in the bag, water from the dough will create condensation. This is normal. Just knead the dough after removing it from the bag, and it will be as good as new. If stored properly, the dough should keep for several weeks.
Making Insulating Play-doh
The Ingredients
- 1 1/2 cup Flour
- 1/2 cup Sugar
- 3 Tbsp. Vegetable Oil
- 1/2 cup Deionized (or Distilled) Water
(You really want to use Distilled water to keep the amount of conductive ions to a minimum. Otherwise, the doh will be conductive rather than insulating.)
Cooking Procedure
- Mix solid ingredients and oil in a pot or large bowl, setting aside ½ cup flour to be used later.
- Mix with this mixture a small amount of deionized water (about 1 Tbsp.) and stir.
- Repeat this step until a majority water is absorbed by the mixture.
- Once your mixture is at this consistency, knead the mixture into one “lump”.
- Knead more water into the dough until it has a sticky, dough-like texture.
- Now, knead in flour to the dough, until a desired texture is reached.
- Store in an airtight container or plastic bag. While in the bag, water from the dough will create condensation. This is normal. Just knead the dough after removing it from the bag, and it will be as good as new. If stored properly, the dough should keep for several weeks.
The idea of creating electrical circuits using Play-doh and the recipes above come from The University of St. Thomas. Check out their Squishy Circuits page for more details.

Is it safe to eat that moldy bread?
Let me set this up for you … it’s Labor day weekend and you’ve fired up the grill with some burgers, brats, or whatever grilled goodness you can think of. You head inside and grab the bag-o-buns and (gulp) notice a few small greenish spots on the surface.
While no one is looking you face the critical decision, do you pluck off the little green spots and serve the buns up, or is it time to head to the store for a fresh set? It’s a hard call, but keep this in mind – the colorful spots you see on food are just the surface spores that allow the mold to reproduce. Just like plants, mold has roots below the surface that can travel deep into the food.
Because the colorful spores on the surface of your food are just part of the mold, scraping or cutting this part off of your bread or bagel won’t save you from eating a mouthful of fungus. While you probably won’t die from eating fungus, keep in mind that foods that are moldy may also have invisible bacteria growing along with the mold.
The colorful mold you see on the surface of food is just the tip of what is going on inside.
Most molds are harmless, but some are dangerous. Some contain mycotoxins. These are poisonous substances produced by certain molds found primarily in grain and nut crops, but are also known to be on celery, grape juice, apples, and other produce. These substances are often contained in and around the threads that burrow into the food and can cause allergic reactions or respiratory problems.
Are any food molds beneficial?
Yes, molds are used to make certain kinds of cheeses and can be on the surface of cheese or be developed internally. Blue veined cheese such as Roquefort, blue, Gorgonzola, and Stilton are created by the introduction of P. roqueforti or Penicillium roqueforti spores. Cheeses such as Brie and Camembert have white surface molds. Other cheeses have both an internal and a surface mold. The molds used to manufacture these cheeses are safe to eat.
What to do if you see mold on your food?
The USDA has a nice chart about how to deal with various foods that are moldy. Check it out for all the details. It breaks down into the two obvious options – Don’t Eat vs. Eat.
Don’t Eat – throw these out if you see mold
- Luncheon meats, bacon, or hot dogs, Cooked leftover meat and poultry, Cooked casseroles, Cooked grain and pasta, Soft cheese
- (such as cottage, cream cheese, Neufchatel, chevre, Bel Paese, etc.) Crumbled, shredded, and sliced cheeses (all types), Yogurt and sour cream, Peanut butter, legumes and nuts, Bread and baked goods.
- Jams and jellies (The mold could be producing a mycotoxin. Microbiologists recommend against scooping out the mold and using the remaining condiment.)
- Cheese made with mold (such as Roquefort, blue, Gorgonzola, Stilton, Brie, Camembert)
Eat – after cutting off the mold
- Hard salami and dry-cured country hams (Eat them. Scrub mold off surface. It is normal for these shelf-stable products to have surface mold.)
- Firm fruits and vegetables (such as cabbage, bell peppers, carrots, etc.) as well as hard cheeses are OK to eat if you remove the mold. Cut off at least 1 inch around and below the mold spot. Keep the knife out of the mold itself so it will not cross-contaminate other parts of the produce.
Remember while you’re preparing all this food, removing mold, etc. that you should be washing your hands and food prep surfaces often. Check out what can be growing in and around the surfaces of your house in this Imagine It! video segment. In short, avoid the molds and wash your hands – often!
Hurricane Science
We hear about hurricanes every year, but how do hurricanes work? Most hurricanes that form in the Atlantic Ocean start as thunderstorms off the coast of Africa. As they travel across the tropical waters around the equator, they pick up moisture and energy, eventually crashing into land where they quickly fall apart.

Hot enough to fry an egg on the sidewalk?
It’s hot outside. Really hot. But is it hot enough to fry an egg on the sidewalk? It’s only a matter of time before you will see someone on TV trying to make this happen. Most likely they will not be successful.
The problem is that an egg needs a temperature of 158°F to become firm. In order to cook, proteins in the egg must denature (modify), then coagulate, and that won’t happen until the temperature rises enough to start and maintain the process. Read more
Fun with Mentos and diet cola
A roll of mentos candies and some cola are all you need for some messy fun when it’s hot outside. It’s become a classic experiment to suddenly release all the carbon dioxide gas from a two liter bottle by dropping the candy inside. In fact, you can release the gas from a bottle of soda with lifesavers, sweet tarts and rock salt just to name a few.
Flashed Face Distortion Effect
The journal Perception reports on an interesting visual effect called the “Flashed Face Distortion Effect.” Apparently an undergraduate student was working on setting up an experiment that required a series of faces all scaled in such a way that the eyes of each image aligned. As he flipped through the images, he noticed that some of the faces began to appear distorted in unusual ways. Researchers are now working on experiments to shed more light on exactly what is happening in the visual processing system to create the effect. Read more
All about fireworks
We talk about how fireworks get their colors everyday in our combustion demonstration at the science center. Something we don’t talk about is what the actual firework shell looks like and how it gets into the air.

How to Make Oobleck
Oobleck is a suspension of cornstarch and water that can behave like a solid or a liquid depending on how much pressure you apply. Try to grab some in your hand and it will form a solid ball in your palm just until you release the pressure, then it will flow out between your fingers. Materials that behave this way are classified as non-Newtonian liquids because their flow properties are not described by a constant viscosity. Read more

Ping Pong Ball Cannon
Using just air pressure – not compressed air – you can accelerate a ping pong ball to amazing speeds. Fast enough to rip through a soda can.
The cannon is a long PVC tube loaded up with a ping pong ball. To fire it off, both ends are sealed with a single layer of clear tape. Next, a vacuum pump is used to remove most of the air from the cannon tube. When the tape nearest the ball is ripped open (punctured by a knife) 14.7 pounds per square inch of air pressure rushes in and slams into the ball. With no air molecules in front of the ball, it can accelerate to speeds of nearly 300 miles per hour.
Of course if the ball does not rip through the can, you can always rip a soda can in half this way.
Floating bag of hot air

A vacuum-packed person
We live in a ocean of air, in fact, we live at the bottom of that ocean of air. All those miles of air above us end up exerting a force of about 14.7 pounds over every square inch of our bodies. We take it for granted since the force per area (pressure) is the same all around us. Things start to get interesting when there is an imbalance in that pressure. What better way to find out what an imbalance in pressure feels like than to vacuum-pack WTVG-13 weekend anchor Christina Williams? Read more

How to make a Naked Egg
A “naked egg” is an egg that has no shell. Let me say that again, an egg with no shell. This is not something you normally run across and even when I show a naked egg to someone they often just don’t get the idea that the shell is gone – yet the egg stays intact. You might want to check out the anatomy of an egg to get an idea what we are dealing with. Read more

How strong is an egg?
Can an ordinary egg support the weight of a 30 pound cement block? That was the question that Jeff and Joe, two of our Team members, were investigating this past Saturday in the Science Studio. They discovered that a single egg is not up to the task of supporting the brick. It just made a big mess on the bottom of the brick when it was crushed. (Actually, a visitor at the Science Studio insisted we try just one egg to see what would happen.)
So the question is how many eggs would you need to support the brick? After cracking a number of eggs in the name of science, the smallest number of eggs they could get to support a block was eight. Check out the video to see how they did it. Read more
The Anatomy of a Chicken Egg
I’ve been poking around the internet and books for some cool experiments and information about eggs in general. I came across this really nice breakdown of the various parts of a chicken egg over at edinformatics.com and have duplicated the information below. I’ve always wondered what those white stringy things (Chalaza) are in my eggs when I make an omelet and now I know not only their name, but also what their function is inside the eggs!
How to rip a pop can in half
Ripping a pop can in half with your bare hands is not all that hard if you know a bit of chemistry and a little about how soda cans are fabricated. The key, is the plastic liner that coats the inside of the can. In order to protect the aluminum can from the carbonic acid in sodas, can manufacturers coat the inside of a can with a plastic liner. The liner also protects the inside of beer cans as well.
Now, I suppose, if you were really strong you could rip any can in half with your bare hands. In order to make it a for-sure thing for this demonstration, I used a bit of chemistry knowledge to etch the can.
How do baby diapers work?
It’s an interesting question. Before 1982, diapers relied on the absorbancy of cotton, paper and sponges to hold the, um, liquid in place. Unfortunately, those materials can only hold about 20 times their weight in water. The average diaper doesn’t really weight that much, so 20 times not very much equals leaks. Read more

Where’s the Bacteria?
We have just passed through the 2011 peak flu season according to Google flu trends as well as the Center for Disease Control. This reminded me that washing your hands is one of the simplest things anyone can do to stop the spread of disease. It’s also one of those things that most people don’t do as often as they should. I thought it would be interesting to test some common surfaces around an office for bacteria. Even better would be to test some spots at abc13 – the host of our Imagine It segments. What do you think would have the highest bacterial count – the toilet seat or the microwave start button? Read more
Supersized Elephants Toothpaste
OK, I have to admit that we really, really like the classic elephants toothpaste demonstration at Imagination Station. Combine a mixture of hydrogen peroxide and dish soap with a catalyst like sodium iodide and you get a foaming tower of, well, foam!
We like it so much that we do it everyday as part of our Method to the Madness demonstration. We have featured it on our weekly science segment Imagine-it on WTVG13 and on an episode of WTOL AM Saturday where we re-branded it “Dinosaur Toothpaste” because of the fossil exhibit we had at the science center at the time. Heck, we have even done it inside a pumpkin for Halloween where it squirts out the face to make a foamy mess. Read more

Cabbage Chemistry
Acid-base indicators provide a great platform for a variety of at home chemistry experiments that anyone can do. One of the simplest indicators that is readily available is red cabbage. It turns out that the colored pigment that gives the cabbage it color is a natural acid-base indicator. The red color of cabbage comes from a molecule called anthocyanin. This naturally occurring dye changes it color depending on the the presence of an acidic or alkaline (basic) substance. Read more

Towers constructed off site are eligible to win as long as they pass the test. Prizes will be awarded to the engineers of the three lightest towers that pass the wind test. Read more
Some people are calling it “Snowpocalypse”
Check out these NASA images of what they are calling one of the largest storms to hit the US since the 1950′s. NOAA also has a great image to give you a sense of the size of the storm taken with the GOES-13 satellite. Some are calling the huge storm a “snowpocalypse“, while others are saying, “This is not a typical winter storm, this is one for the history books,” – Thats from Edward Fenelon, a meteorologist with the National Weather Service in Romeoville, Ill. How much snow did you get? Let us know in the comments below.
