Gas Law Demonstrator (LSE) New! The discovery of the Gas Laws goes back aways - to 1662, to be exact. But it needn’t take a few centuries to understand the concepts. Despite the deceptive simplicity of our design, you can verify both Boyles’ Law and Charles Law to a high degree of accuracy. To prove it, we’ve provided sample data in our instructions.   This set contains a syringe; two wood blocks for Boyles Law experiments; one wood block with two holes for performing Charles Law experiment.
