DAM aka Directional Attack Mine

The DAM uses 30 size 64 rubber bands to shoot 50 K'nex purple connectors up to 100ft with the slightest pull of the trip!

Nice! I might build this! One question, have you ever considered explosives? They work well for Nerf... You know the little party popper that has the string pull on the end? They work rather well.

Never considered it cause I like to use K'nex and Rubberbands to power all my ideas

Ehh, no prob. I might try it though...

Oh, I see how this works. It kind of uses the squeeze shot mechanism like in Kinetic's KLS V.2. The trigger is simple yet very strong.

Yeah simple sturdy mech and yet the trip is super easy to set off. Took awhile to find that balance

It seems like the pin would snap under 30 bands. It's amazing that it has a light release trigger but is almost impossible to malfunction.
