Explore how to make a lightweight, porous, and insulating aerogel alternative at home using simple materials to mimic the remarkable properties of real aerogels.

This experiment builds a small thermoelectric generator using a Peltier module to show how temperature differences can be converted into electricity, highlighting the Seebeck effect, performance limits, and applications from waste heat recovery to space exploration.

This experiment uses cornstarch or gelatin with binders to create translucent samples that model transparent ceramics, demonstrating how composition and microstructure influence light transmission, strength, and optical clarity compared to advanced materials like ALON or spinel.
