Put this around the two wheels and connect to the two white peices.

Step 10: Loading And Firing.

Pull the elastic band back around the white and blue rods then put the bullet in and hold in place with a blue rod. Then put the elastic band around the bullet and relese the blue rod! This fires about 20ft if you have the correct elastic band size! Thanks. Subscribe for more.

Nice cool disine
Cool, I like it!
Maybe you could try to make a real trigger, that blue rod looks pretty unrealistic.
