SpringBots: 3 in 1 Spring-Powered Machines

# 139762
$29.99 Buy Now

Build a motorized robot, race car or a countdown timer with the Thames & Kosmos SpringBot science kit.  Each of these machines run without any batteries or electrical power! The secret behind these fascinating machines is a power source called a mainspring - a spiral shaped spring that stores up energy when wound up by hand, and then converts that stored energy back into motion when it discharges.  The robot marches forward on two legs.  The race car zooms across the floor.  The countdown timer is a bit more complex and slowly ticks down the seconds for up to 6 minutes. Discover the physics concepts of potential and kinetic energy.  Easy, snap-together assembly.  133 pieces.

Ages 6 (with help) and up.
