A brass needle for the famous pin-through-the-balloon effect. After inflating a transparent balloon, take a large crochet-type needle and pass it through a balloon. After demonstrating that the balloon is invulnerable, the needle is removed from it, but the wool thread also passes through the balloon, leaving the balloon dangling for a few moments.

After having also removed the wool thread on purpose, it will be popped with the same tip. The effect is complete. A large brass needle 46 centimeters long is provided with instructions for creating the effect, with 10 transparent balloons included.
