Here’s a great way to use waste from a party and promote recycling. Take one soda or beer can, adorn it in motors, gears, and decorative features, then add
a battery. Voila! You have your very own Tin Can Robot.
This gift, which costs $9, is pretty out there as far as presents go, but has to be better than socks, right? At the very least, it makes a funny gift for
a geek who already uses “real” circuit board kits like Arduino, or perhaps a geek-in-the-making child who can’t quite
be trusted with a soldering iron just yet.
