Picture of Cheap/Easy Rubber Band Powered Launcher! 100m+
This is a rubber band powered launcher that can fire over 100m (330ft) depending on the quality of the finished product and the ammunition used. I will try to add a video of it in use sometime soon.

This is my first instructable, i am sorry for any flaws and blurry photos.

I take no responsibility for any damage to people, items etc. caused by this device.

Step 1: Materials

Picture of Materials

You will need:

The thickest rubber bands you can get.(size 109= $5-7 from most stationary stores)

Ideally a small pringles can but anything like that will do. (try to get something that is sturdy)

Scissors or knife

Masking or duct tape (optional, but will increase life of the rubber bands)

Step 2: Tie the rubber bands together.

Tie about 5 to 10 rubber bands together, but I recommend about 7.
 Repeat so you have two lengths of rubber bands.

Step 3: Making The Ammo Cup

Make a hole large enough for the rubber bands to fit through. (remember to make space for the knots to slip through when tying)
If you are using a thin plastic cup you might want to put tape on the edge of the hole so it doesn't cut the rubber band. (see pic)

Step 4: Finishing Off

Now feed one of the bands through the hole and and tie together.
Make sure the rubber band isn't twisted or uneven where you tied it.

That is a tiny bit of overkill... If it went 100 meters I would be amazed
