Food calories are a measure of how much energy is contained in the food item. A very graphic way to visualize how much energy is in a handful of food is to burn it and observer the flame. We try this with a handful of cheesepuffs and Total cereal using liquid oxygen as an oxidizer.
This week Sloan and Jay create a couple of foam volcanoes using a solution of concentrated hydrogen peroxide and some dish soap. Using super concentrated solutions allows the reaction to happen so fast that the foam literally hits the ceiling in our demonstration theater. Check out the video and learn about an at home version.
Methane is a flammable gas that is lighter than air. Often fire fighter have to worry about not only flames that come from the ground, but also dangerous flammable vapors that are lighter than air.
Take a trip back to the 1970′s and make your very own lava lamp using just stuff you have around the house. It’s mesmerizing…
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.
Did you eat a few to many chips loaded with a spicy dip? Perhaps just to much during the Game (Ohio vs. Michigan) and are in need of a bit of antacid relief? Check out this video to see just how an antacid works to reduce the acid level in your stomach. One thing I forgot to mention is that Milk of Magnesia is also a laxative … so with all meds read the label before consuming…!
While it looks like Sloan is changing water into wine, what’s really taking place is a chemical clock reaction. Two reactions take place at the same time – reaction number one is trying to create a dark liquid, reaction number two is consuming a chemical needed to turn the liquid dark. After a few seconds the second reaction runs out and the liquid turns an inky black.
A little alcohol in a 5 gallon water jug will combust in an interesting way when a flame is dropped inside.
Super absorbers were developed in the 1960′s by the Department of Agriculture as a product to spread over crops to even out the drench-drought cycle. This class of polymers is capable of absorbing up to 400 times their weight in water. This amazing ability to hold liquids in a gel eventually led to their use in baby diapers, plant soil, grass seed and those fun “grow creatures” toys that swell in water.
What happens if you tilt a room’s floor at 25 degrees, but keep the rest of the room (door frames, windows, etc) at the correct perspective? We call it distorted gravity – or maybe that is more what it feels like. Your eyes and ears get conflicting signals and that can lead to only one thing – a queasy stomach. It’ something you just have to experience in person to fully appreciate.
What would happen if you created a chemical reaction inside a carved pumpkin that generates a whole lot of foam? Watch the video to find out. Question is, what reaction would you choose? We thought it would be fun to use a 35% solution of hydrogen peroxide (that’s more than 10 times more concentrated than what you have at home) and some soap to catch the oxygen gas that is generated.
Solid carbon dioxide is often called dry ice because at normal atmospheric pressure it never forms a liquid state. Instead of changing from a solid to a liquid and then to a gas, it jumps right from solid to gas. This is called sublimation. Dry ice is very cold, around 109 degrees below zero on the Fahrenheit scale. That’s cold enough to freeze flesh and cause frostbite which it why we always wear gloves when handling this stuff.
Sodium Alginate is derived from seaweed and is used as a gelling agent in many foods. We think it’s just fun to play with! When you add the alginate solution to a calcium chloride salt solution it turns into a jell nearly instantly. If you are careful you can make tiny spheres (or caviar balls) if you drip it, but if you squirt a solid stream, it will turn into a “wormy” tube with a solid exterior and a liquid filled interior. Some pretty crazy stuff!
The Boyo is a unique experience – you become much like a yo-yo where you do all the moving. It looks simple enough, you add some energy to the overhead flywheels and then they pull you off the ground a few inches. If you keep adding energy by pulling on the handles, eventually you will be pulled 13 feet off the ground. It takes a bit of practice, so don’t expect to get to the top in one, two or even six pulls.
Flammable liquids can generate invisible vapors that are also flammable. These vapors can be more dangerous than a liquid spill because they are invisible and can travel a distance to an ignition source. Imagine you spill some paint thinner in your basement, as you clean up the liquid, the vapors can move across the floor to a pilot light. As the vapors ignite the flames will flash back to the liquid spill – and you!
These ceramic tiles protect the space shuttle as it renters the Earth’s atmosphere at speeds over 17,000 miles per hour. They are capable of withstanding temperatures as high as 3,000 degrees Fahrenheit as the orbiter returns to the surface. A secondary purpose for the tiles is to protect the shuttle from the alternating heat and cold experienced while orbiting the earth. They are amazing insulators!
This is one of our newest exhibits. You have all seen the footage of a TV meteorologist standing outside in some crazy winds reporting on a severe storm or even a hurricane. This exhibit allows you to safely experience winds up to a category one hurricane. If things feel a bit to extreme for you you can simply step out of the wind blast – something you can’t do in a real hurricane.
