The last week I was at a coffee shop in Santa Maria and realized that if you lay out a fork, knife and spoon with the fork in the middle you can force the fork. While this isn’t the best stand alone trick as it’s a force of one object out of three and there is potentially some process involved, but it’s something that would be handy to have in your brain in case you ever need it.
Ask someone to touch one of them. If they touch the fork, you’re done. If they touch the knife or spoon, you have them spell that item, moving from one item to the next (forward/backwards) to an adjacent item for each letter. Due to the number of letters and how the math plays out it, they will always end on the fork (if they do it correctly).
You’ve now forced the fork, you can use that however you want.
