Just popped into the Royal Institution for a coffee, to discover they have a lovely display on benzene to mark the bicentenary of Faraday's discovery of it. Here are his notes, his paper, and one of his first samples. Glorious.

Adding polymers to a liquid speeds up its flow through a pipe by reducing the frictional drag at the pipe’s inner surface. Now researchers have found that the polymers also suppress eddy formation and thus reduce the loss of flow energy to heat.

Polymers Tame Turbulent Flow
New experiments show that adding polymers to a fluid can reduce energy dissipation by suppressing small eddies.
