The Kitchen Is a Lab

Every kitchen has ingredients for dozens of fascinating experiments. These teach chemistry, physics, and biology through hands-on discovery.

Layer honey, dish soap, dyed water, and oil in a glass. Different densities create a rainbow stack.

Write with lemon juice, let dry, hold near a warm bulb to reveal. Oxidation turns juice brown.

Drop raisins in carbonated water. Bubbles lift them up, pop, and they sink. Teaches buoyancy.

Oil and water in a bottle, add food coloring and Alka-Seltzer. Colored blobs rise and fall.

Dissolve salt or sugar in hot water. Suspend a string. Crystals form over days.

Pepper on water, dip soap-covered finger. Pepper rushes to edges as surface tension breaks.
