Needle Through Balloon
You can't beat an effect that looks impossible, and such an effect is “Needle Thru Balloon”. Spectator blows up an ordinary balloon, ties it off and gives it to the performer. Magician takes a long metal needle with a ribbon at the end and OPENLY sticks the point in at one end and pushes it through to the other end of the balloon! All can see the needle going through (it really does!). Needle is removed, balloon is tossed into the air and popped! Everything included.
