Some fun science experiments that you can do at home

Here are some fun and safe science experiments that you can do at home with common household items:

1. Homemade Lava Lamp: Fill a clear plastic bottle with water and leave some space at the top. Add vegetable oil until the bottle is almost full. Drop a few drops of food colouring into the bottle. Break an Alka-Seltzer tablet into smaller pieces and drop one piece into the bottle. Watch as the coloured bubbles rise and fall, creating a lava lamp effect.

2. Magic Milk Experiment: Pour some milk into a shallow dish or plate. Add drops of food colouring to the milk. Dip a cotton swab into dish soap and then touch it to the surface of the milk. Watch as the colours swirl and mix as the soap disrupts the surface tension of the milk.

3. Homemade Slime: Mix together equal parts of white school glue and liquid laundry detergent in a bowl. Add food colouring or glitter for extra fun. Stir until the mixture starts to come together and form a slime-like consistency. Knead the slime with your hands until it's smooth and stretchy.

4. Baking Soda and Vinegar Volcano: Build a volcano using modeling clay or playdough around a small plastic bottle. Mix together baking soda and red food colouring inside the bottle. Pour vinegar into the bottle, and watch as the mixture erupts and flows down the sides of the volcano.

5. Static Electricity Butterfly: Cut out a butterfly shape from a piece of tissue paper or thin plastic. Charge a balloon by rubbing it against a fabric surface like a wool sweater. Hold the charged balloon near the butterfly shape and watch as it sticks to the balloon due to static electricity.

6. Rainbow in a Jar: Fill a clear glass with water. Carefully pour different liquids with varying densities on top of each other, such as honey, corn syrup, dish soap, water, vegetable oil, and rubbing alcohol. Watch as the liquids layer on top of each other, creating a colourful rainbow effect.

7. DIY Cartesian Diver: Fill a clear plastic bottle with water, leaving some space at the top. Make a Cartesian diver by partially filling a plastic pipette or eyedropper with water and sealing it tightly. Place the diver inside the bottle and screw the cap on tightly. Squeeze the sides of the bottle and watch as the diver sinks and floats depending on the pressure.

Remember to always follow safety guidelines and supervise children when conducting science experiments at home. Additionally, it's a good idea to clean up thoroughly after each experiment and properly dispose of any materials used. Have fun experimenting!
