Bee Police


If someone asks you to name an animal that helps the police catch thieves and solve crimes, you're likely to say the dog. A dog has a good sense of smell and can be trained to chase and catch criminals.

It turns out that other animals are good police helpers too. In the United States, honeybees are being trained to detect bombs. A bee has a super-sensitive power of smell. Bees are even better than dogs when it comes to searching for explosives.

Experts that are training the bees give the animals sugar water. Little by little, they add tiny amounts of TNT to the sugar water. TNT is an explosive that is used in bombs. That way, the bees are trained to link the smells of sugar and TNT, and will think where they smell TNT, there is also sugar water waiting for them. In this way, the bees can help police find dangerous bombs.

One problem the experts have to solve is that bees still love the smell of flowers and other sweet things, which could sidetrack them in their search for bombs!
