This experiment examines how the sound propagation of a mechanical egg timer behaves under normal pressure compared to an evacuated desiccator. The egg timer is triggered in both environments, and the perceived loudness as well as possible sound alterations are analyzed. This investigation provides insights into the acoustic properties of gases and their significance for …

The Catalytic Effect of Ash on the Combustion of Sugar
This experiment investigates the catalytic effect of ash on the combustion of sugar. Initially, an attempt was made to ignite a sugar cube with a lighter, which was unsuccessful. Likewise, ash alone could not be ignited. However, after sprinkling ash onto the sugar cube, the mixture burned with a blue flame. This indicates that certain …
