2. Magic Milk Experiment
Concept: Surface Tension and Chemical Reaction
Materials Needed:
- A shallow dish
- Milk (whole milk works best)
- Food coloring
- Dish soap
- Cotton swabs
Instructions:
- Pour milk into the shallow dish.

3. Homemade Lava Lamp
Concept: Density and Immiscible Liquids
Materials Needed:
- A clear bottle or jar
- Water
- Vegetable oil
- Food coloring
- Alka-Seltzer tablets
Instructions:
- Fill the bottle about 1/3 with water.
- Pour vegetable oil until the bottle is nearly full.
- Add a few drops of food coloring.
- Drop in an Alka-Seltzer tablet and watch bubbles rise like a lava lamp!
4. Static Electricity Balloon Experiment
Concept: Static Electricity
Materials Needed:
- A balloon
- Small pieces of paper or a dry cereal like Rice Krispies
Instructions:
- Blow up the balloon and rub it on your hair or a wool sweater.
- Hold the balloon near small paper pieces and watch them stick!
- Try moving the balloon near hair and watch it stand up!
5. Invisible Ink with Lemon Juice
Concept: Acid Oxidation
Materials Needed:
- Lemon juice
- Water
- Cotton swabs or a paintbrush
- White paper
- A heat source (lamp, candle, or iron)
Instructions:
- Mix equal parts lemon juice and water.
- Use a cotton swab to write a message on the paper.
- Let it dry completely.
- Hold the paper near a heat source and watch the hidden message appear!
6. Rainbow Walking Water
Concept: Capillary Action
Materials Needed:
- 6 clear cups
- Water
- Food coloring (red, yellow, blue)
- Paper towels
Instructions:
- Fill 3 cups with water and add food coloring: red, yellow, and blue.
- Place an empty cup between each colored water cup.
- Fold paper towels and place one end in a full cup and the other in an empty cup.
- Watch as the colors “walk” through the paper towels and mix in the empty cups!
7. Balloon Rocket
Concept: Newton’s Third Law of Motion
Materials Needed:
- A balloon
- String
- A drinking straw
- Tape
Instructions:
- Tie one end of the string to a stationary object.
- Thread the straw through the string.
- Inflate the balloon and tape it to the straw.
- Release the balloon and watch it zoom across the string!
8. Oobleck (Non-Newtonian Fluid)
Concept: States of Matter
Materials Needed:
- Cornstarch
- Water
- A mixing bowl
Instructions:
- Mix about 2 cups of cornstarch with 1 cup of water.
- Stir until the mixture turns into a gooey substance.
- Press hard on it to make it feel solid, then let go and watch it turn into liquid!
9. Dancing Raisins
Concept: Buoyancy and Gas Formation
Materials Needed:
- Clear glass
- Carbonated water or soda
- A few raisins
Instructions:
- Fill the glass with carbonated water or soda.
- Drop raisins into the liquid.
- Watch them dance up and down as bubbles attach and release!
10. Egg in a Bottle Experiment
Concept: Air Pressure
Materials Needed:
- A hard-boiled egg (peeled)
- A glass bottle with a mouth slightly smaller than the egg
- A piece of paper
- Matches (adult supervision required)
Instructions:
- Light a small piece of paper and drop it into the bottle.
- Quickly place the egg on top of the bottle opening.
- Watch as the egg gets sucked into the bottle due to changing air pressure!
