ELI5: If something is absolutely frictionless, could you touch/hold it?

Yes, out of the Nvidia physics demo video!

Sure. You wouldn't really be able to grip it (it would slip out), but you could encase it in your hands, or you could hold it using variations in its shape. For instance, if it was a cross shape, you could wrap your fingers around the center portion and it wouldn't be able to slip out, since it would have to pass through your fingers to do so.
