Friends and family will gasp in horror as they view the carnage; your window is riddled with bullet holes! Sniper in the area? Wise guy taking pot-shots? Those death threats becoming a reality?
Don't worry, the neighbourhood is not rapidly going down hill, they are Fake Fun Bullet Holes. Yes, watch as your chums soil their undergarments at the very thought of dodging that small arms fire.
Okay, I know they only look like BB shot holes, but from a distance they can give the unsuspecting victim, er I mean friend quite a surprise.
I am not an expert in the damage small arms fire makes. I would imagine some bullets just leave a large hole in the wall but this will do for the time being.
Step 1: Supplies
Drinking straws (the bendy ones are best)
Clear water based glue stick
or Saliva (sorry, this is not as bad as it sounds)
