Likewise, chess and checkers teach logical thinking. The airtight pool toy demonstrates principles of buoyancy. The planter demonstrates hydroponics. The gift box doubles as a Faraday cage. The tensegrity hovercan demonstrates tension vs. compression in a fun way. Aluminum sheeting can make a wifi reflector. The Mobious strip is the best starting point for exploring the mathematics of topology. The resonator stand and clicker are all about sound generation, reflection, and acoustics. Nearly every Aluminoid could be used to launch a discussion of metal fatigue, material failure, elasticity, and deformation.
And the Aluminator is great for teachers. You can make inexpensive prizes for the best test score, most improved student, or best essay. Aluminoids make a great project for art classes, summer camps, Boy Scout troops, Girl Scout troops, Sunday School activities, school carnival prizes, and the like.
