Hands-on chemistry experiments are engaging, but sourcing materials safely and affordably can be a hurdle. What's a clever substitute or household item you've used successfully in a home or classroom lab?
Red cabbage juice makes a perfect pH indicator for home experiments It is safe cheap and changes color with acids and bases so you can see reactions without fancy reagents
Vinegar and baking soda let you show gas evolution safely without buying fancy reagents and they clean up easy
Corn starch and water make a fun non Newtonian fluid for a quick rheology demo You can squish and pump it and it behaves oddly without any lab plastics
Coffee filters work as cheap chromatography material for simple color separations You can compare dyes from foods and it teaches chromatography without special labs This aligns with home science experiments 2025 guide
A kitchen scale helps measure tiny masses for experiments When the real balance is out of reach it brings a slice of lab like precision to the kitchen
