This month's, our Read It and Eat Book Club books were all robot-themed
(Robot Dreams by Sara Varon, House of Robots
by
James Patterson and Chris Grabenstein, and Curiosity by Gary
Blackwood). We followed our discussion with a brush bot activity. I had ordered electric toothbrushes though a dollar store, and I bought 72 little fingernail brushes through Amazon. I initially thought I'd be able to easily pop the motors out of the toothbrushes, but in the end (after a lot of one-on-one time with needle nosed pliers), it seemed most practical to leave the motors in the brushes. I was able to snip the heads off with a wire cutter pretty easily.
I had anticipated attaching the toothbrush motors to the fingernail brushes with duct tape or hot glue, but thankfully the curved handles of the fingernail brushes fit exactly around the body of the toothbrush. It was basically a miracle.
We experimented with using one fingernail brush, two fingernail brushes, even four fingernail brushes. And we added all kinds of decorations! We had lots of fun, and I think this activity would have occupied the kiddos for hours.
One word of advice: have a few extra batteries on hand! The toothbrushes come with batteries, but some are duds. It would have been great to have a few extras to pop in.
