Magic Tricks

Realistically, you need to do a little bit of crafting at home to get prepped for this trick, but once done you should be able to do this trick multiple times with almost no pocket space needed.
It does have limits on what straws work, clear straws are no good. White straws don't provide a good contrast with white paper covers, although I think they can work. You may need to provide a straw from some other place, although I don't think that will ruin the trick. The straw is fully examinable at the end, so the fact that it doesn't match the other straws probably wouldn't even register with most people, and if it does you can just claim that the cafe must have changed straw suppliers.
