This is by far the most visual and cleanest version of jumping rubber band effect, no doubt.
BJ1 or BJ2 is pretty practical to perform in real world, even surrounded (of course you need to
know your angle). I've performed to normal people as well as magicians, it all worked well. BJ3 is
for advanced learner. I seldom do a direct BJ3. I did BJ1, then BJ2, then you can continue with
TOUCH as it jumps to the audience hand as a finale.
If you have chance to see Hanson do it
live or in other magicians' videos, you'll realize it's still doable for live audience and it looks
great. But it really needs practice.
BJ4 needs a bit preparation and more for video
shooting. But it gives you the idea of the mechanics of rubber band magic. In real world
performance, just like what Hanson did in the trailer, BJ3 with a reverse jump will make a 4 times
jumping effect.
