A banana trick seems to be an appropriate way to start off this blog… This is a way to amaze the whole room by giving someone a banana that it has already been sliced inside!
You will need a banana that is ripe enough to already have some black spots on it, so that the tiny holes you will put in the skin won’t be noticeable. Then you need a very fine needle that is long enough to go from one side of the banana to the other, threaded with about 30cm (12 inches) of thread.
The idea is to put a loop around the banana, but inside the skin. You will notice that the banana has 5 or 6 or so ‘corners’. Push the needle into the banana at one corner, and run it under the skin through to the next corner, and out. Pull the thread through, but leave a tail of thread at the beginning. Now push the needle back into the hole it just came out of, and through to the next corner. This time leave a little loop at the corner where your needle went in. Continue in this way around the banana, until your needle comes out of the hole where you started. You now have a loop around the banana inside. Now you pull gently on both the ends of thread that are emerging from that one hole. The thread will slice the banana and get pulled out of the hole. Be careful when pulling the ends that you pull them in the directions in which they are already travelling, otherwise they can tear the hole.
