Messy fun, you’ll agree, if you've ever seen kids playing with magnets and iron filings, or sharing them in a science class. Our each is 3/8 oz, which is approx 146 gazillion filings, and pure hell to clean up unless you have one of our handy-dandy aforementioned magnets!

We love obsessives. Mike Rigsby, author of Amazing Rubber Band Cars (124pp, soft cover) has spent way too much time designing and building rubber band cars. His book has designs for (13) rubber band cars, all built from simple materials (cardboard, pencils, a few CDs, and the eponymous rubber bands) and made for speed, distance, or goofiness. Well-illustrated, with easy-to-follow directions, it culminates with a giant, you-can-sit-in-it car that he swears will work. Send us a picture.
