We carry quite a few utility items and routines involving the defiance of gravity. Here's a quick review on a couple to help you choose what's right for you.
Floating Match on Card or Cosmosis by Ben Harris:
If you've never played around with floating or levitation effects, this is a great place to start. Floating Match on Card comes with two gimmicks in case on breaks. Cosmosis is the "magician's" floating match on card routine. It comes with the gimmick, supplies to make more gimmicks, and an excellent instruction booklet.
Strengths: Easy to carry around visual, unexpected magic. One of the few levitation tricks with no "hook-up".
Weaknesses: It's delicate. Very delicate.
Floating Dollar Bill by Jon Jensen:
The first routine with an "IT Hook-up" that I would recommend. It's eerie, visual and simple. Ball up the bill and watch it go.
Strengths: It's done with a borrowed object which is examinable before and after the trick.
Weaknesses: After setting up the trick you are limited with where you can perform it. Anytime you want to make something float, you have to be standing in the same spot.
Hummingbird Card by Magic Makers:
This is a floating card effect similar to the UFO Card or the Hummer Card trick. This is another great introduction to IT effects.
Strengths:It looks really cool and can be done anywhere.
Weaknesses: I've never felt safe with this hook-up in place. Maybe I just haven't gotten used to it, but if I'm doing walk around, I've got a lot more to worry about than a very invisible delicate thing running across my body.
I.T.R.s i.e. Thread Genie by Magic Makers and Spider Pen by Yigal Mesika:
Reels are great for walk-around because you can set it up and take it down anywhere you go. The effect usually looks just like the Floating Dollar bill, although there are other hook-up variations possible for tricks like floating ring, floating match, and haunted deck.
Strengths: They both are very portable. The Spider Pen uses an electric reel and has more flexibility in control and distance between performer and floating object.
Weaknesses: Both are delicate and require practice. Repairing a break can be frustrating at best with the Thread Genie, it's easier with the Spider Pen.
Enlightenment by Ben Harris:
This one doesn't really fit in with the rest of the tricks in this segment, but I've had a lot of questions about it, so here it goes... A selected (could be signed) card rises off the pack and then floats back down for full inspection.
Strengths: No thread is used and the card can be examined before and after the effect. The bold performer can even perform this trick while the spectator is holding the cards.
Weaknesses: The angles are great, but the trick is certainly not angle-proof. Unless you get the Development Kit, Custom Deck, and/or the Paradigm Shifter, you've got some construction and hunting-down-of-materials to do.
If you made it through the whole post, congratulations. This one was a doozy!
