Three cool web sites to spend your money on....

http://www.sciplus.com/ - just cool science things. Very amusing text
http://www.widgetsupply.com/ - best gadgets and hobby tool site around!
http://www.firefox-fx.com/ - firework and rocketry site. One of the few sites still selling chemicals, so probably an FBI front :-) Buy your oxidizing agents while they are still legal! :-)
