18 Easy Science Experiments Using Materials You Already Have On Hand

  1. Baking Soda and Vinegar Volcano: Create a volcanic eruption by combining baking soda and vinegar in a container. Watch as the mixture fizzes and overflows, demonstrating a chemical reaction.
  1. Lemon Battery: Use a lemon, copper and zinc nails, and wire to create a simple battery. Connect a LED light or small electronic device to show how fruit can produce electricity.
  1. Rainbow Walking Water: Fill three cups with water and add different food coloring to each. Connect the cups with paper towels to create a capillary action that “walks” the water up the paper towels, creating a rainbow effect.
  1. Egg in a Bottle: Place a peeled hard-boiled egg on top of a bottle with a small opening. Light a piece of paper on fire and drop it into the bottle. Watch as the egg gets sucked into the bottle due to the change in air pressure.
  1. Invisible Ink: Use lemon juice or milk as invisible ink. Write a secret message on paper using a cotton swab dipped in the juice. Heat the paper gently to reveal the hidden message.
  1. Oobleck: Mix cornstarch and water to create a non-Newtonian fluid called Oobleck. Explore its properties by applying pressure and observing its solid and liquid-like behavior.
  1. Mentos and Coke Explosion: Drop a few Mentos candies into a bottle of cola. Observe the explosive reaction caused by the release of carbon dioxide bubbles.
  1. Homemade Lava Lamp: Fill a clear container with water, vegetable oil, and food coloring. Add an effervescent tablet (like Alka-Seltzer) to create a mesmerizing bubbling effect.
  1. Magnetic Slime: Mix school glue, iron oxide powder, and liquid starch to create a magnetic slime. Use a magnet to manipulate the slime’s movements.
  1. Surface Tension Magic: Pour water into a plate or shallow dish. Carefully place a paperclip on the water’s surface, demonstrating the concept of surface tension.
  1. Coke and Milk Reaction: Pour milk into a bowl and slowly add Coca-Cola. Observe the chemical reaction between the milk and the acidic soda, causing the milk to curdle.
  1. Balloon Rocket: Attach a string to two points, then blow up a balloon and tape it to a straw. Thread the straw onto the string, release the balloon, and watch it zoom across the string due to the release of air.
  1. Floating Egg: Fill a glass with water and add enough salt to make it dense. Drop an egg into the water and watch as it floats due to the change in density.
  1. Homemade Fireworks: Use a small piece of aluminum foil and place it on a burner. Watch as the heat ignites the aluminum foil and creates a mini fireworks display.
  1. Dancing Raisins: Drop raisins into a glass of carbonated water. Observe as the carbon dioxide bubbles attach to the raisins, causing them to float and “dance” in the water.
  1. Lava Lamp Science: Fill a jar with water, oil, and food coloring. Add an Alka-Seltzer tablet and watch as the mixture creates a lava lamp effect due to the release of gas bubbles.
  1. Crystal Garden: Create a crystal garden by placing a piece of porous material (like coal or a sponge) in a container with a saturated salt solution. Over time, crystals will form on the material.
  1. Rubber Egg: Submerge an egg in a cup of vinegar for several days. The vinegar will dissolve the eggshell, leaving a rubbery egg that can be bounced and manipulated.
