Bubbles

What you need:

• 1 gallon of water

• 1 teaspoon of Guar Gum

• 2 teaspoons of baking powder

• 3/4 cup of Dawn dish detergent

What you do:

1. Add baking powder to the water.

2. Add the Guar Gum to the Dawn dish detergent. Then, add this mixture to the baking powder and water.

3. Mix vigorously, but try to avoid making foam on top.

4. Grab a bubble wand and get ready to see the biggest bubbles.

Tip: This recipe improves with time as the Guar Gum fully hydrates and dissolves in the water. You'll see the bubbles get even bigger in a day or so.

What's the science:

Have you ever tried blowing a bubble with only water? Then you know it's an impossible feat. Water has a unique property called cohesion, which refers to the attraction of water molecules to one another. Cohesion is responsible for the surface tension that causes water to form spherical droplets. That's because water molecules would much rather clump together than stretch out into a bubble.

That's where the Dawn dish detergent comes in! The dish detergent separates the water molecules, reducing surface tension. Then, the water is much more willing to form big, beautiful bubbles, rather than clump together.
