The floating card on wand gag (where the card is stuck on end of wand that is tucked under your arm)

What do they use on end of wand to make card stick?

Thanks in advance

Wax

Joshua that was funny. Thanks Trickytrav

I bet that would stick it to the wand =)

Blue-tak.
I purchased orange-tak and after the stuff gets dirty a bit it just blends right into the color of my wand and it isn't even noticible. To make it re-tacky, just take if off, work it around a bit and put it back. Mine's been on there for a few years now.

Wax is probably a bad idea unless you're applying it just before using it.
Heat, smearing, yuck ....

Blue-tak, baby!!!

Last time I was the craft store I found something they called "Sticky Dots." They are 1/8" thick clear gummy things about the size of a shirt button. You can't "knead" them the way you can Blue Tak, but they work extremely well.

They are also available as Glue Dots, in 3 different degrees of stickiness (Permanent, removable and poster) and they are useful for lots of things magical (In fact, if you dig out your copy of Sam Berland's 20 Tricks with WizTax, you'll find these dots are a great substitute for the old wig tape that Sam used to sell) By the way, the permanent glue dots aren't all that permanent, they still rub off clean.
