Fun Science Experiments for Kids

Ha ha, why draw a straight line in front of a hen?

The hen looks like it's been hypnotized.

It lies there without moving at all.

Draw a circle on the pan with garlic.

The egg will come out perfectly round.

Rub your fingers on a peeled garlic clove,

then you can easily pick up an egg yolk.

It's all because of disulfide bonds.

Place a glass in front of the girl,

then fill it with water.

The girl will appear to turn around.

That's how light refraction works.

Pour a little liquor onto some sand.

Sprinkle sugar and baking soda on top.

Light it, and you'll summon the ancient pharaoh's serpent.

Bend shape memory metal any way you want.

Drop it in hot water and it returns to normal.

That's the magic of shape memory metal.

Press your fingerprint onto white paper.

Then pour a little iodine solution into a cup.

Spread it evenly with a paper towel.

Place the cup upside down over the print.

Keep heating the cup with a hair dryer.

The fingerprint will slowly appear.

You just learned how to lift fingerprints.

Fill a bottle one-third full of water, then drop some small rocks into it.

Just keep adding more rocks.

Even when the bottle is completely full, not a single drop spills out.

So how did the crow drink the water?

Cut a chocolate bar into pieces, then secretly rearrange them like this.

Somehow there's an extra piece.

Now you'll never run out of chocolate.

Add some milk to a glass of cola.

Wait for half an hour.

The cola actually turns clear.

It also creates some mysterious sediment.

Would you still drink milk and cola together?

Sand the paint off an aluminum can.

Suspend the can over an empty cup with a stick.

Pour some drain cleaner into the cup.

Let it sit, then take it out.

You'll see that the can has turned transparent.

Place a matchstick beneath a magnet.

Hang a bottle from the matchstick.

Use another matchstick to spread the string.

Make the string form a triangle.

Place another matchstick through the middle.

Now remove the magnet from the table.

The bottle stays perfectly balanced on the edge.

That's the principle of lever balance.

Rest a syringe between two bottles.

Shine a laser through the water droplet.

You just made a simple microscope.

It works like a convex lens.

Roll a piece of paper into a tube.

Angle it over a glass. Light the top, and the smoke flows downward.

This is reverse flow smoke.

Place two matches together and light them.

They look like a couple deeply in love, holding each other tightly, and refusing to let go.

Only have one battery for your remote?

Use a wire to bridge the empty battery slot.

The remote will work normally again.

Wrap a piece of wire around a key.

Connect both ends to the battery terminals.

You just made an electric hot knife.

That's resistive heating.

Attach magnets to both ends of a battery.

Place it inside a closed copper coil.

The battery starts moving on its own. That's how an electromagnetic train works.

Wrap copper wire tightly around a screw.

Connect it to a battery and it becomes magnetic.

That's how an electromagnetic crane works.

Attach a magnet to the battery's negative end.

Place a copper coil on the positive end.

That's the basic principle behind an electric motor.

Place two pencils into a cup of salt water.

Connect their tops to the battery terminals.

You'll see water split into hydrogen and oxygen.

That's electrolysis. Don't toss expired gum.

Shape it into a cone.

Catch the gum off guard and smash a coconut down onto it.

The coconut actually gets punctured.

That's the power of a non-Newtonian fluid.

Dip a cotton swab in onion juice.

Write a secret code on white paper.

The numbers only appear after being heated.

That's the secret behind invisible ink.

Pour some leftover cooking oil into a glass.

Then add some water.

Squeeze in a little red food coloring.

Finally, drop in three fizzy tablets.

Wait for a moment. You'll see a beautiful underwater volcano erupting.

Draw sea creatures on a plate with a dry erase marker.

Then pour some warm water into the plate.

The drawings magically come to life.

That's water surface tension.

Bend some matches in the middle and group them together.

Place a drop of water in the center.

They'll slowly form a perfect five-pointed star. That's water tension at work.

Add sugar and dish soap to a glass.

Then mix everything well.

You can blow bubbles that won't pop easily.

Go ahead and try it yourself.

Peel the striker strip off a matchbox.

Light it on fire.

It leaves behind a brown, oily residue.

Rub a little of it gently on your hand.

It will produce white smoke. That's how magicians make smoke with bare hands.

Add baking soda and white vinegar to a glass.

The mixture produces carbon dioxide.

Bring this invisible gas close to a candle.

The flame will suddenly go out.

That's the basic principle of a fire extinguisher.

Instead of letting kids stare at phones and TV,

do these fun science experiments together.
