BUZZIN ROULETTE

THE EFFECT: You are able to determine which of four paper cones has a buzzer underneath it

HOW TO DO IT

For this trick you need:

• Four sheets of A3 paper
• Four paper plates
• One Britains got Talent buzzer (available online or in gadget shops)
• Some sticky tape
• A needle or pin
• A volunteer

PREPARATION

1. Make a cylinders out of the four paper plates. Put sticky tape on one of the shorter edges, and attach to the other shorter edge without folding the paper. Use the tape to attach a paper plate to each cylinder
2. Before you begin the trick, make a pinprick in one of the plates (Get an adult to do this if necessary) as an identifying mark. You are now ready to perform

PERFORMANCE

1. Show the Britain's Got Talent buzzer and tell the audience that you want to avoid hitting it until the end of the performance. If you hit the buzzer, the performance is over. 
2. Put the buzzer underneath the cone that has the mark on top.
3. Get a volunteer to go up on stage and shuffle the cones until they are sure you do not know which one has the buzzer underneath. Hopefully, they won't notice the secret pinprick, and will keep the buzzer under the marked cone at all times.
4. When they have shuffled the cones accordingly, come up on stage. A quick glance at the cones will tell you which one is marked and has the buzzer underneath.
5. Hover your hand over the cones, then crush one of the unmarked cones with both hands
6. Repeat this for the other unmarked cones
7. When you have crushed all three unmarked cones,take the marked cone of the buzzer and show that you have made it to the end of the performance without hitting it
