Got lazy kids, friends or even parents? If so, then this is a sure fire way to get them out of bed. The new sonic grenade won't blow them to smithereens but it will trigger them to get up.

Just pull the pin out of the grenade and throw it in the general direction of your target. The grenade siren will sound and the only way to switch it off is to replace the pin back in to the grenade.

The Sonic Grenade is an ingenious way of waking people up but should be used carefully.

Not suitable for young children.
