Most Dangerous Object: PET Bottle Launcher

Instant messaging with a co-worker

all day long can get repetitive.

Mix it up and try sending them a message on a bottle

with the RPG-7 PET bottle launcher.

It's the most dangerous object in the office this month.

This RPG-like toy from Japan allows you

to do a shoulder-mounted take

on the classic middle school physics demo.

Just clip a one liter bottle to the end of the tube,

attach a bike pump to pressurize the contents,

aim, and pull the release latch.

Maybe sending a follow-up text message wouldn't hurt.
