#2740: DriftDye

Drifting cars is now a common form of entertainment.

Today’s invention is a drift car tyre which is made with different coloured dyes embedded within its layers.

As the performance continues, the crowd gets to see changes in the colour of smoke produced. It might be possible to achieve a similar effect by attaching a disc to each wheel so that, as it spins, the outer edge rubs on the road and generates eg pyrotechnic effects or just frictional sparks.

There could even be a colour of tyre dye chosen to indicate that a lower safety limit had been reached.
