The 19 strangest gadgets

From USB hand warmers to a spy pen

Take a walk on tech's wild side with some of the strangest, most original, and most bizarre gadgets you've ever seen. We've got vacuums for your lawn, swimwear that can charge your iPod, and grenades that don't explode but still go boom.

Sonic grenade

This grenade may not explode, but it can still make a lot of noise. Just pull the pin, toss it, wait about 20 seconds, and the grenade lets out an annoying beep that puts your alarm clock to shame.

To silence it, hold down the trigger arm or replace the pin. The sonic grenade has three volume settings and is powered by three AAA batteries. Buy it from Firebox for £9.99.

Disinfection scanner

It may look like a flip phone, but this device claims to kill 99.9 percent of all bacteria and viruses.

All you have to do is open up the Nano-UV Disinfection Scanner and wave its nano-UV light over anything that needs disinfecting for 10 seconds.

Ideal for combating creepy crawlies that might be hiding in mattresses, pillows, or carpets. The gadget costs £35, is just one inch thick, and is powered by two AAA batteries.
