Fear not
Today when I was at school, I was performing with my loops. I found the perfect shade outside and I had about ten people watching. I dediced to do one more trick. So I borrowed someones glasses, I put them down on the ground and made them rise. While they were rising one of the people came up and put his hands on top of the glasses and broke the string. I said I was done. Everyone leftr but him, He came to me told me that he felt the string. He told that if I wouldn't give him one he would tell how I was doing those tricks to everyone. What should I do?
If I had a dollar for everytime i performed something as silly as a double lift and someone said "Oh, i know how you did that" and when asked how or handed a deck, they couldn't reproduce or explain anything, I'd have at least the next 4 semester's tuition in the bag.
Saying "I felt the string" is a far cry from "I saw the string" or even worse, "I have your string." Another thing, I've been working with loops for a short while and I lose them while they're sitting across my fingers. There's little to no way the guy felt the loop- more likely he's heard of magicians doing tricks with invisible thread and just said that to get your reaction. I prefer to use the default ed norton line from the movie
The Illusionist, "That is one way it could be done," whenever thrust into a situation akin to that. Doesn't give anything up, does make the guy look like a jerk- win win
Let the guy explain whatever he wants away and do one of two things
1) shrug it off and in conjunction with hand picked, gullible audience members, confidently use an alternate hookup with your loops (lateral levitations or trigonal setups rather than horizontal or just go old school with the thread and read up on the many setups possible with that stuff (i.e. around your ear, over the shoulder, around your glasses, in your cheek etc...)
or
2) don't perform something using thread or loops for a week or so, let stuff cool over in that respect. Tomorrow when you go back to school say that you'll step it up a notch and do something better than levitating objects, you'll do it yourself and go right into a king's rising or what-have you (king rising only popped into mind because here in NY, it's been wicked cold the past few days so i found myself using the jacket i was carrying in the halls to class as the initial cover for the trick and getting a good five inches before BioChem started)
Either way, there are a myriad of ways to levitate an object so don't fret. Keep up the good work and remember to have fun with the people, don't sweat being caught (unless your hands are being burned by a suspected naysayer and it's a nacky move). Fearing being caught leads to you looking at your own hands leading the audience to watch your hands leading to your tricks being reduced to recess entertainment.
Chillax, have fun and keep amazing
