How to play
Tap it to make it twist and writhe.
Notes
Tie a knot in a string and join the two ends, and you get a loop that can never be untangled without cutting it; the trefoil crosses itself three times. Mathematicians study knots like this in a field called knot theory.
Tap it and waves of swelling loops run around the tube, lifting and twisting it as it glows pink, then it settles back into its trefoil. Real neon signs glow because electricity makes the gas inside the glass tube shine; pure neon glows red-orange.
