Mars Rover Pack 30 Piece

The glow-in-the-dark pieces are the real winner here — my son turns off the lights and the whole rover still glows on his nightstand. Magnets snap together tight enough that his creations don't fall apart when he zooms them across the floor.

My 6-year-old has built about four different rover designs since yesterday and keeps narrating fake Mars missions while he snaps the magnetic pieces together. The glow effect after lights-out is a nice bonus, though he insists on keeping it by his bed now.

The glow-in-the-dark pieces are the real winner here — my son builds a new rover every night and insists on turning off the lights to watch it glow before bed. The magnets snap together tight enough that his creations survive being driven across the carpet, which honestly surprised me.
