No more dull lessons! From now on, bowels of teachers and other people will decorate your street view!
Now what to do when some prof or teacher is harping on the same subject a bit too long to your taste and doesn't want to give a break, or when your neigbor's face doesn't please you? Just push the buttons and jam the rotating propeller in his/her stomach! Immediately all bowels will be removed from his/her body and flung into the air.
What's more, this device is very economical and contains a catalyser, so you won't hear any complaints from Greenpeace. Only the cleansing-service may have some objections, but you know what to do in such cases...
As for outfit, we only recommend goggles to prevent the spattering blood and meat from getting into your eyes. Waterproof clothing is also recommended (except when you believe your washing product is really as fantastic as publicity claims).
