Making Yellow Butter.

We must emphasize the word "yellow".

It's very easy to make butter. The problem is that children are not very impressed with butter that's not yellow. Personally, I find it hard to blame them. Here's how to give your butter a nice rich colour.

Blowing up Balloons

When vinegar and baking soda are combined they produce a gas called Carbon Dioxide.

1. Put about 3 teaspoons of baking soda into a plastic 250ml bottle. Add some vinegar until the bottle is nearly half full.

2. Quickly stretch a balloon over the top of the bottle. Shake the bottle and watch the balloon inflate.
