Science and Inquiry discussion

Hello all,

I am looking for some simple and fun Psychology experiments that could be done at a party.

The experiment could have anything to do with perception, fallacies, "mind" or similar(not chemistry or physics) .
For an example, The rubber hand experiment is an ideal experiment for what kind of experiment im looking for.

Thanks a lot

Edit: Btw i hope this post did not break any rules since it has nothing to do with books
