hey man, thanks for sharing! Looks like they really enjoyed it.
Is it open to some feedback? If not, feel free to ignore what's below:
-Sponge balls never look normal, because people have never seen them before. so I would avoid asking them if it looks normal. If they say yes to you, they are just lying (see video "why magic works" by Penn & Teller)
- Personally the Wilson's counting routine looks good, but makes very little sense as to why you start counting.
- you mention that you were cheating and that you have an extra ball. I know that's not truth, however, I would submit that it deconstructs the previous work you have done with them. They no longer amazed at how you made balls travel from your hand to theirs, they are wondering at what point you introduced the extra ball (In my opinion of course).
- it looks like they were enjoying themselves which means you were doing a good job with them. Overall, nice work and thanks for sharing!
(Again, just some feedback to think about, but take it with a grain of salt, and use what you will)
