Unfortunately it's only strong enough to pop balloons. But it's a good start!
(the fun starts at 1:29)
Sweet!
It didn't rotate when used against the balloon ...for a reason ;)
Only the upper laser should be switched on, giving an 'usage voltage overloaded' pulse (and semiconductor cools down while its rotate one full circle while air streams over its cooler fins which lead the heat away from the semiconductor (actually the laser can make multiple spins and when it has cooled down enuf for the next pulse it fires when in position one , so gun can spins faster then the visible rate of fire )... then it would not only look mean, it would allow to overpower the laser ...well a little ...and would make use of the gattling design :)
We can check off invasion by alien ballons as a threat.
