Then i hot glued the straws to the spool and then hot glued paper to it straws . the sicence behind the deminstration is the forse of the person who will rotate's it will the forse spins the axle and moves the wheel and moves the straws and the paper makes the wind.

The Clean -o-Bot

The clean-o-Bot is my complex machine it has a pully and three wheels and axles .All you have to do is type the instructions and the Clean-o-Bot does it . There is a mini camera above the claw so the Clean-o-Bot can see. The claw grabs it and drops it in a big funnel shape and closes the lid to the funnel. There is a very small hole and air flows in . As the air compresses the purple lid flips up and shoots the object in it's rightful spot. The wheel and axles help have it able to reach all the objects in the room or where it is tolled to be. The claen-o-bot is for ages six and up for spelling resones .This machine is very good for busy people. The claen-o-bot can go on any serface from rocks to hardwood .The clean-o-bot would sell for 159.99 American.
