I bought a couple of 'magic jellyfish' (or Cartesian divers) to amuse my grandson. I was disappointed to find they needed a little more strength to squeeze the bottle than my grandson possessed and he couldn't make them float and sink without assistance. I have rigged up a simple tourniquet using a length of ribbon and a wooden spoon to make it easier to operate. I then remembered watching one of Thomas Kim's videos on making a simple Cartesian diver from a drinking straw and some drawing pins so I decided to make some of my own.
