i think you need to put some glue

i try it and i adjust it a bit.I put a switch at it .it look cool. but the eraser did not attached to the motor .it broken i need to exchange it anytime

I made one in year 5 as a last minute project in a piece of telephone pipe because the motor fit in the end exactly and the battery pack as well, then I just dremelled in a thing for the switch and painted it yellow... High 5 for being slack and getting an A!. Great instructable, very well written with good, clear pictures. Excellent work

In 3rd grade, we had a show and tell. I forgot to bring something in, but found a dime in my pocket... guess what my show and tell was. I was extremely resourceful as a kid... My show and tell consisted of spinning the dime and timing how long it spun before stopping. I said that each coin had it's own average spin time (depending on the person spinning it), but I had lost my other coins. Considering the cool projects the other kids bought in (K'nex ball roller coaster being one of them), they still seemed to have flocked around the dime just to watch it spin. Now that's being slack :P

I built a lego conveyor once and made it measure the weight of stuff and it would then change its speed. that was in year 4 at my primary :)

whats does inavative mean???
