Good stuff! Need more simple practical things like that - it is really interesting.
Slight side topic: Bit of "biology" I've been experimenting with at home based on stuff I had lying around. Works really well...
Items: 2l coke/water bottle, 2l Cheap apple juice (preservative free), sachet instant bakers yeast, 100g sucrose sugar, sterlising tablets, balloon.
Steps: Empty coke/water down the drain or gob, sterlise bottle, put everything but the balloon in it, screw lid on and shake for a couple of mins, take lid off, prick hole in ballooon and stick on bottle neck so it inflates, leave in warm cupboard for a week, put a couple of teaspoons of sugar in it, screw normal lid on and shake, leave for 2 days, put in fridge for 4 hours, drink, fall over :)
In case anyone didn't follow, this is a recipe for alcoholic carbonated apple cider. So easy a kid could do it! The part to be careful about is the carbonation step where you put in more sugar and put the lid on. If you put too much sugar its possible that the bottle will explode.
