Dear Matt,

Relying on a gadget blog that uses "gadgets" and "madness" as their motto for your homework can be tricky and difficult. We might tell you the truth, or we just might tell you that green lasers are filled with magic fairy dust and the Hulk's underpants.

The best way to get your homework done is by reading books at a library. Course we never actually went to the library to read books either, so we suggest you try this link:

Your other option would be to order a couple from ThinkGeek and open them up and look inside for fairy dust.
