It's possible to induce charge in things - this principle is used for holding silicon wafers inside lithography machines but works for other materials too (https://youtu.be/pgV8l5yLadQ)
Or on the other side you remind me of a literal party trick - a rubber balloon filled with helium that's starting to deflate and thus has neutral buoyancy can be moved around without touching it. The charges on the surface of the balloon and on your hands repel.
