The document summarizes an experiment to determine how long it takes slime mould to solve a simple maze. In the experiment, slime mould was placed in a maze constructed from Lego pieces and its progress was observed over time. It took the slime mould approximately 34 hours to solve the maze, which was longer than predicted based on its maximum growth rate of 1.8 cm/hr. Possible reasons for it taking longer than expected include multiple environmental changes, room temperature conditions instead of an incubator, and initial lack of nutrients. The document also provides background information on slime mould and details on how to properly culture and grow it.
