A safe version of our "Elephant Toothpaste" demonstration you can try at home.

You'll Need:

• a 500ml narrow necked clear bottle
• a small funnel
• 100 ml or 1/2 cup of vinegar
• a squirt of ultra liquid dish soap
• food colouring & glitter (optional)
• baking soda
• a spoon
  

What to do:

1. place the bottle on a flat easy to clean surface, large shallow tub or sink
2. using the funnel, pour the vinegar into the bottle, then remove funnel
3. add soap (and colouring / glitter) to the vinegar and gently swirl the bottle to mix them
4. add 1 - 2 spoons of baking soda into the bottle.
   

What's Going On?
The vinegar is an acid and baking soda is a base. When they mix, a chemical reaction takes place, producing a gas which causes the fizzing and churns up the soap to make foam.

Safety
Keep your face distant from the mouth of the bottle.
