4 Fun Experiments for Kids
Why not try these fun experiments with the kids, they will be amazed!
Experiment #1
You will need one or two eggs, some scotch tape, a stocking, and a pot of water.
Before starting the experiment, you should ’inspect’ the egg with a flashlight. It will be easy to seen through. Then wrap the egg with the scotch tape firmly and thoroughly.
Take the stocking and place the egg approximately in the middle of it on the inside, twist the bits of stocking on both sides.
Take the stocking by both ends and twist the egg around its axis. You can check whether the egg is ready for the magic using a flashlight. You can boil the egg when it becomes shadow-proof.
Cook the egg without removing the scotch tape, turning it from side to side. Boil the egg for 10 minutes then allow it to cool down, and peel off the shell. You’ll end up with the miracle of an inside out egg!
Experiment #2
You’ll need gummy worms, baking soda, vinegar, a cutting board, a sharp knife, and 2 glasses.
Cut each worm into 4 pieces. It’s a good idea to wet the knife first with water to prevent anything from sticking to the blade. Dissolve 3 tablespoons of baking soda in warm water.
Put the mini-worms in the baking soda solution and wait for about 15 minutes. Pull them out and put them into the glass with vinegar in it. They will immediately be covered with bubbles, start ’dancing’, and rush to the surface.
How it works:
When you put the worms that have been moistened in soda into the vinegar, the acetic acid reacts with the bicarbonate (from baking soda). Bubbles of carbon dioxide appear on the worms, pulling them to the surface and making them twist. On the surface, the bubbles burst and the worms drop to the bottom, which produces new bubbles that push them to the surface again. For the best results, try using about 4 worms at a time, so that they can ’dance’ freely in the glass.
Experiment #3
You’ll need 5 small cups, 1 cup of hot water, a tablespoon, a syringe and a curious child with a sweet tooth. You’ll also need some skittles: 2 red, 4 orange, 6 yellow, 8 green and 10 purple ones.
Pour 2 tablespoons of water into each glass. Pick the required number of skittles and put them into the glasses. Hot water will help the candy to dissolve faster. If the candy dissolves slowly, put the cup in the microwave for 30 seconds. Then let the liquid cool down to room temperature.
Using a syringe, pour the coloured liquid into a small glass jar, starting with the most dense color (purple) and ending with the least dense color (red). Drip the syrup in carefully, otherwise all the layers will get mixed up. It’s better to make the droplets go on the side of the jar and let the syrup flow down slowly. As a result, you will get a rainbow-like juice out of Skittles.
How it works:
The secret is in the density of the syrup. The thicker and heavier layer moves downwards faster, while the less thick syrup rises to the surface.
Experiment #4
You’ll need a lemon, a cotton bud, a bottle, any jewelry of your choice (hearts, sequins, beads) and lots of love.
Squeeze a bit of lemon juice into a glass, then dip the cotton bud into it. Use it to write down your secret message.
To reveal the message you should heat it (by ironing it or holding the paper over the fire or in the oven). Be sure not to allow your children to try to do this on their own.
How it works:
Lemon juice is an organic substance which can be oxidized (reacts with oxygen). When heated, it becomes brown and burns faster than paper. Orange juice, milk, vinegar, wine, honey and onion juice have the same effect.
