Why Our Experts Love It
We all want to get a little green. So, when we saw a clock that runs on water AND the kids get to build...well...WINNER! If you haven't seen Snap Circuits, well, you ain't seen nothing.
Pick one up. They are the best 'science experiment' kits we've found. Sometimes they cost a little more, but they are worth it. All the pieces are compatible with other Snap Circuits.
