About: Hi im kevin! i make stuff =] Kthanksbye =D
I BUILT THIS FOR THE I MADE IT CONTEST!! As you can see i posted it the day of the deadline :)

This is my new creation! It is coin operated and designed for quarters.
If you drop in a penny, nickle or dime, it will just take your coin. :)
For every quarter, one gumball is dispensed.
                     
Please read:
I also built lock and key mechanism for safely storing the collected change.
Unfortunately I didn't have enough knex to finish the rest of it :((
I ran out of green rods and 3D connectors.

So i am left with a random lock and key system with no way to attach it to the bottom of the machine.
I Hope the Coin Operated Gumball machine alone is enough :)

    Thats totally false. In the other video you can see better that you don't introduce the quarter. It is just a mechanism that makes that always you turnthat thing, a gumball cames out.
