Truly mad scientists must have come up with this idea: create tiny robots by strapping motors to toothbrush heads. But, boy, were our testers glad they did! Kids snap together the two 'bots, then turn on the vibrating motors that make the 'bots careen and cruise. The accompanying book offers ideas for 12 activities, including racing (build lanes from the included paper punch-outs) and painting (see above). Bonus: kids can decorate the Bristlebots to look like bugs with the kit's wire and beads.
