Lately our kids have been obsessed with lava, each day they hop around our furniture saying “the floor is lava”. 😂
So in true dental style, we are ending #scienceweek on a high by creating volcanic toothpaste.
Firstly we created a TOOTH CITY artwork which includes little teeth as people, mouths as housing blocks, a toothbrush drive through, gum tree park, crown shopping centre and a big volcanic toothpaste in its centre.
The volcanic toothpaste erupted today using our experiment but it did save tooth city as it was at risk of decay!
Our method:
- A glass jar or cup (capacity 500ml)
- 1/2 cup hydrogen peroxide liquid (6% solution)
- 1 tbs dry yeast
- 3 tbs warm water
- 1 tbs liquid dishwashing soap
- A few drops of food colouring
- Small cup
- Safety glasses
- Tooth city artwork (optional)
Steps:
- Pour the hydrogen peroxide into the jar followed by food colouring, and dishwashing liquid.
- Carefully swish around the jar to mix.
- In the separate cup add water and yeast mix.
- Pour yeast mix into the jar with the hydrogen and watch the toothpaste slowly erupt!
Notes:
- Take care when handling the hydrogen peroxide – should only be handled by an adult.
- Use warm water not hot.
- The foam will overflow so be prepared or place the jar on a tray.
Let’s get erupting!
