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???

John Smith (author)sonnimo1232007-11-23

He means innovative.

with all due respect i did the same thing by poking a hole on an eraser and sticking it on the end of a handheld fan with the propeller off. So simple.

Callum Snowden (author)Colonel882010-12-29

Yeah but this version looks as if it would take a bit more abuse and it isnt as big...

badrang4 (author)John Smith2007-11-24

thank you (im just a 6th grader!)

Colonel88 (author)badrang42008-11-07

Great work!!!!!!!!!!!

ultrauber (author)2008-04-07

Wait. Don't you need to attach a real eraser to the bottom so that it actually takes stuff off?

sonnimo123 (author)ultrauber2008-04-11

you can but i did use a real esaer but just a small one:)

ultrauber (author)sonnimo1232008-04-11

Oh. So you mean, you attached a little eraser to the bottom? Or did you just mount the whole thing inside a eraser?

sonnimo123 (author)ultrauber2008-04-11

no i just made a hole in the bottom of the easer and hot glued it to the motor for a snug fit:)

sonnimo123 (author)2007-11-22

thecreator (author)2007-11-23

!Andrew_Modder! (author)2007-11-23

LOL thats original. :-P you could mabe make it better by adding a switch on the side to turn the motor on, instead of the wire touching. Oddly Cool Instructable.
