It is a very easy and funny science experiment,which results in rapid eruption of huge amount of foam.surely,it is one among the top funny science experiment for kids.
Reagents and equipment
Level:beginner level (for kids)
1. 10% hydrogen peroxide
2. Food coloring
3. Dish soap
4. Yeast
Level 2:Intermediate level
1. 20% hydrogen peroxide
2. Food coloring
3. Dish soap
4. Saturated potassium iodide
Level:3 Ultimate level
1. 35% hydrogen peroxide
2. Food coloring
3. Dish soap
4. Saturated potassium iodide
Procedure
1.Take a round bottom flask, add hydrogen peroxide,.food coloring and dish soap.
2.Then add either yeast or saturated potassium iodide solution ,which results in a rapid eruption of huge amount of foam. It resembles tooth past.
Process
Elephant tooth paste is the decomposition process of hydrogen peroxide. Yeast potassium iodide works as a catalyst to break down the hydrogen peroxide into oxygen and water. Soap will then mixed with the oxygen and water,which turn into foam.
H2O2→H2O + O2
as the concentration of hydrogen peroxide increases, more foam is emitted.
