- Paper aeroplane (what could be simpler?)
- Weird goop (ok, it’s a polymer)
- Sugar glass (the stuff they break over people’s heads in movies)
- Hero’s engine (from a Coke can)
- Stirling engine (more complex, also from a can)
- Van de Graaff generator (yet another Coke can project)
- FerroFluid (I’d love to have some of this stuff, but some of the ingredients are a bit beyond kitchen chemistry. You can find sources in Google.)
- Vacuum pump (from fridge compressor)
- Homebuilt submarines, submersible semi-autonomous robots and ROVs (fantastic stuff, but where would you begin?) (UPDATE - ROV in a box)
