PLEASE I NEED A NEW MAGIC TRICK IDEA! I WOULD APPRECIATE ANY SERIOUS IDEAS!?

Hi, I'm a magician and I want to make my service unique in order to get more bookings, I'm a parlour or street magician so it needs to use portable objects. Please give me IDEAS for tricks involving one or more of the following props: envelope, zip lock bag, cards, coins, string, thread, nails, sponge , rubber bands, my arm, my head, my neck, my eye, rings, necklaces, shoe laces, water bottle, phones, balloons, wallets or my pulse. PLEASE use one or more of those props because those are PERFECT for street magic. I DO NOT need links to places where I can learn magic I need YOUR ideas please!
