A couple of weeks back Naomi asked if we could do some science experiments. Natually this strongly appealed to me, so we duly obliged. We had a go at learning how an airplane wing works with a piece of paper, seeing water surface tension in action, and making some bubbles by mixing acid and alkali. Here is the latter...

Fill balloon with bicarbonate of soda (alkali)

fill bottle with vinegar (acid)

seal balloon onto bottle, and pour alkali into acid 
the reaction makes carbon dioxide, which makes bubbles and blows up the balloon
