en.wikipedia.org/wiki/Double_pendulum
the double pendulum is chaotic for high amplitude oscillations. it's possible to compute the motion numerically using a computer. There's no analytical description so one has to simulate the path. A symplectic integrator would do nicely.

make a dubble pendulum and run a physics
simulation on it. Wonderful things, computers.

the problem in discussion was "does the temperature of a metal ball bearing affect the fall velocity through liquid nitrogen?"
The physicists went and did an inconclusive experiment and argued about it. I just said that the problem had been solved years ago and they just had to look up the answer.
They told me to stop spoiling it.
