Fun story, you can NOT kill a bug in front of my 5yr old. He'll cry himself to sleep at night because 'that was a NICE BUG !!!!!!!'
I've used lots of things to kill a bug; flyswatter, rolled up newspaper, flip flops, and a dish towel just to name a few. My husband is scarily accurate with those super thick rubber bands that they use to hold bunches of broccoli together. We always seem to have one in the kitchen 'junk' drawer.
This is definitely a new one, but I see myself trying it the next time I have to get rid of a pest. It seems like there's a smaller margin of error in the aim which is always my problem. I also appreciate how good her aim is while also filming. Props.
