Add-A-Tread
And save someone's neck. This deeply textured safety tread is diamond-plate-pattern black rubber, 17" x 3-7/8" x 1/4" thick, with a peel-off self-adhesive back. It can be cut, but won't easily crack or tear. A great way to add traction to truck bumpers, RV steps, ladder steps, etc.

Your New Hydrogen Ride
OK, you can't ride in it, but your gerbil can. From the excellent Thames and Kosmos® company, now comes this Fuel Cell Hydrogen Powered Car. You add (2) "AA" batteries to aid the electrolytic process, but after assembly and the right priming, the hydrogen cell will power this 8" x 5" open-frame vehicle. For ages 10 and up, the kit includes a detailed 16pp instruction booklet. Good for physics instruction and good for science projects. "Today the gerbil, tomorrow the whole family!"
