Some gifts get a polite smile; these get a crowd. Each one does something surprising the moment it's switched on: an engine that runs on heat, a steam engine that spins, a magnet that holds an object in mid-air, a coil that plays music through lightning arcs.
Most work within minutes of unboxing, so they're ready to show off on the day rather than after a weekend of building.
