Weird World: check out the world's oldest condom

The oldest surviving condom in the world has gone on display in an Austrian museum. The reusable condom dates back to 1640 and is completely intact, as is its original users' manual, written in Latin. The manual suggests that users immerse the condom in warm milk prior to its use to avoid diseases. The antique, found in Lund in Sweden, is made of pig intestine and is one of 250 ancient objects related to sex on display at the Tirolean County Museum in Austria this summer.
