This experiment combines the two things everyone loves. Lots of bubble foam and an EXPLOSION! It’s one of our favorite experiments! Today we’re going to try and make the biggest reaction.
- ALWAYS WEAR GOGGLES AND GLOVES
- DO UNDER PARENTAL SUPERVISION
- DO OUTSIDE
You will need…
- A large, clean beaker
- 50 mL of 35% hydrogen peroxide
- 10 mL of potassium iodide
- Liquid dish washing soap
- 5-10 drops of food coloring
- Small cups
- Safety goggles
Pour your measured ingredients into small cups
Add 35% hydrogen peroxide
Add your dish soap and food coloring
Carefully add your potassium iodide and BACK AWAY QUICKLY!
Elephant toothpaste is the decomposition process of hydrogen peroxide, while yeast/ potassium iodide works as a catalyst to break down the hydrogen peroxide into oxygen and water. Soap will then mix with the oxygen and water, which turns into foam.
