This one does not require IT, but it does require something extra.
That something extra could be
finicky to carry with you - but that is more of a personal preference.
If you want a
balancing trick, see Tensegrity in PH's AOA, Joshua Jay's Penguin 2 lecture, or Rick Lax's Vertigo.
If you want to balance a bill, try this, but it is a bit underwhelming.
DC did a
similar trick for Lee Hawkins on TV, and that is more fun.
