This is a nice looking book that has lots of science experiments such as blowing up a balloon with a banana!!! Very adventurous, and no nitrogen rich fertilizer or plastic explosives necessary. I know one very prominent New Zealand scientist who blew other things up when he was a kid and it didn’t appear to harm him too much…

Btw, did you notice how hard it is to buy a plastic gun for a boy these days? Of course, kids that have these things taken away by the left (hand) just replace their fun using the right hand of Xbox and Nintendo and Playstation (and probably obesity to go with it).

PS. I hope you are using Google Books to find information and book previews. The book mentioned above for example has a few experiments that you can read online.
