Fun innovative STEM set, setting challenges to build different types of detector.
Build your own ingenious metal detectors based on basic circuitry principles with this clever 35-piece set from Explore Science. Build a handheld metal detector with lights and adjustable sensitivity, then test with various metal objects. Create a mini security check station that can scan objects, just like at the airport. And set up a maze challenge, needing a steady hand as you carefully move your way along the metal wire, avoiding setting off the buzz alarm if you touch it. Explore the wonders of engineering and electricity - the perfect present for bright sparks!
