3 experiments were in store for us.
The apparatus we would be using.
All 3 experiments can be conducted at home as all the materials are readily available.

Place the folded paper into the water and observe how the paper unfolds as water is absorbed.
Bend at midsection but do not break the toothpicks
Arrange the toothpicks as above. Place 3 drops of water into the centre using a dropper.

Shake and swirl the bottle. Observe the tornado. If the tornado is not visible, add in more detergent.
We had a bonus experiment.
The kids got to see a rubber glove expand using baking soda and vinegar
5 teaspoons of baking soda, a few squirts of vinegar, tie up the end of the glove quickly and Ean had himself a balloon :)
