coilgun

Entertaining vid:

Coil guns are really cool, but I wish they were way more powerful.  The projectile travels way too slowly.. the highest velocity setting is 145 ft/s. If you’re not familiar with projectile speeds, to put it into perspective a 9mm bullet travels at around 1200 ft/sec.

2:46 – 😂 the golf ball.  Ouch.. that hurt to watch haha.

3:10 – Me: *bracing for the can to go in the head.. then slowly ooze out like the golf ball did*

Always enjoyable vids from this guy.  One of the few channels I have notifications turned on for.
