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 creates superhydrophobic surfaces using wax, paraffin, and powders to mimic the lotus effect, demonstrating how surface chemistry and microstructure combine to repel water through bead formation, high contact angles, and self-cleaning behavior.

This experiment investigates how wearing different numbers of cotton hoodies during a 30-burpee workout affects insulation, heart rate response, and recovery time to heart rate homeostasis.

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.

This experiment creates and tests composite materials reinforced with carbon fiber to evaluate their strength, durability, and flexibility compared to traditional materials.
