This is my specialty actually!
About a month ago I was at a camp for special needs children that can't walk or talk very well. I wanted to put on a show where I made it look like I had "enchanted" them thus giving them powers to pull off pretty cool stuff.
My go to effects for this are Siberian Chain Escape ( I do a variation where a spectator gets locked up by another spectator and a blanket is thrown over them and magically they have escaped once it's removed), Sleeper by Eoin O'Hare, Double Deception Deluxe by Bob Swadling and Mark Mason, Electric Touch+ by Yigal Mesika (I use it to pretend that it is the "power" I am giving them), Pyro by Adam Wilber (I use it with their hands over mine for a powerful mental effect), Perfect by Mark Mason, Surge by Mickael Chatelain, and my very own No Pressure can be done by the spectator.
Hope that list is a good start for you to find something works for you!
