Common kitchen ingredients can demonstrate real chemistry and physics concepts. These experiments are safe, cheap, and produce impressive results.

8 Kitchen Science Experiments

Baking Soda Volcano: Mix baking soda, vinegar, and food coloring. Classic for a reason.
Oobleck: Mix 2 cups cornstarch with 1 cup water. It is both a solid and a liquid.
Dancing Raisins: Drop raisins in clear soda. Carbon dioxide bubbles lift them up and down.
Milk Color Burst: Pour milk on a plate, add food coloring drops, touch with a soapy cotton swab.
Crystal Growing: Dissolve sugar in hot water, hang a string in the jar. Crystals form in days.
Lemon Battery: Stick a nail and a penny into a lemon. Connect wires to light an LED.
Invisible Ink: Write with lemon juice, heat the paper to reveal the message.
Density Tower: Layer honey, dish soap, water, and oil in a glass. They stack by density.

Safety Notes

All ingredients are household-safe. Adult supervision needed for hot water and cutting lemons. Clean up is easy—everything goes down the drain or in the compost.
