1. The orbs are roughly a metre in diameter. There is some minor size variance within that, perhaps a few cm either way.
2. They are hovering unless acted upon.
3. If moving slowly, you could get your hand into the orb. You can push up to your wrist before it solidifies too greatly to continue. Retrieving your hand at that point is more of the same - don't panic, stay slow.
4. Upon being hit with electricity, the power flickers through the orb, and then dissipates. No visible reaction. Looks pretty cool, though.
