6 SCIENCE MAGIC TO DO WITH WATER
super easy
Kids love doing water activities, and doing experiments with water is like a cherry on the top. With some learning with fun activities, your kids can learn and play at the same time. Water is one of the
greatest mediums of exploring science. It’s readily available, It’s safe, and kids love playing with it. Here are some fun water projects to do with water.

1.Walking water experiment:
You must have seen water flowing; now see this science magic of walking water where water walks from one container to another container and that too without any external force.
Materials required:
- 2 containers fill with water
- A tissue paper
- Few different marker colors
Procedure:
Fold the tissue paper in a long strip so that it can be easily dipped into the containers.
Color both the ends of the strip with 2 or 3 different colors.
Now dip that paper towel into the containers so that it goes from one container to another container.
We made tiranga with this experiment.
Explanation:
This science magic is called capillary action. It is a process when liquids like water move up through a solid, like a hollow tube or a spongy material.
Through capillary action, the water moves upwards through the paper towel, also lifting the food dye molecules with it present in the paper towel. This same phenomenon is what allows trees to get water from the ground with their roots.
2. Rising water experiment
What actually happens when you place a glass over a lit candle in a bowl of water? Well, the result will be like magic, and kids love watching the magic. It will reveal the hidden property of air that’s around you all the time.
Material required:
- A shallow bowl (we used a tub here)
- Water
- candle
- A glass
Procedure:
Set your candle on the plate and pour some water, just enough to dip 1/4th portion of the candle.
Light your candle, then place your glass upside down the candle.
Then sit back and watch the magic happening.
As the flame of the candle goes out, all of the water is sucked up into the glass, and water rises.
Explanation :
The flame heated up the air trapped in the glass, causing the flame to go out. After the candle flame gets extinguished, within few seconds, everything cools down. The cool air acts as a vacuum, causing the water to rise. Once you lift the glass up, the waterfalls back into place.
3. Upside down glass of water
Turn a glass filled with water upside down but don’t let its waterfall out. Can you do that??
The secret to doing this trick is hidden in this experiment.
Materials required:
- Glass filled with water and
- a thick piece of paper to cover the entire mouth of the glass ( we used an invitation card here)
Procedure:
Fill your glass with water and make sure that water is filled completely to the top of the glass. If there is any space between the water and the card, the experiment will not work.
Gently place the paper on the top of the glass.
Now place your hand over the paper and flip the glass upside down.
Gently remove your hand from the paper and see the magic.
The paper stays there, and water doesn’t spill out.
Explanation:
This is because the air pressure on the card from underneath is greater than the weight of the water inside the glass. This is why the card manages to hold up and doesn’t let the water spills out.
4. Coin drop experiment:
What about dropping a coin into an empty glass in a creative and scientific way??
Let’s do this then…..
Materials required:
- An empty glass
- A coin
- A thick piece of paper that is long and wide enough to cover the entire mouth of the glass
Procedure:
Cover your empty glass with a piece of paper, then put a coin on top of it.
Now flick the card with your forefinger in a horizontal direction.
The result- the coin will not move with the card but will drop into the empty glass
Try doing this with more stacks of coin and note the results.
Explanation:
It explains Newton’s first law of motion and inertia “An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an outside force”.
The coin has inertia, meaning it really wants to stay in one place. If you move the card slowly, it isn’t fast enough to overcome that force. If you flick it quickly, the coin stays in one place and then drops into the glass.
5. Water temperature experiment:
With this experiment, show your kids the thermal energy in action and explain to them the concept behind it.
Materials required:
- 2 glasses of water, one is hot water, and the other is cold water.
- 2 food colors
Procedure:
Fill one glass with hot water and the other glass with cold water.
Now add the few drops of food color simultaneously in both glasses.
You will see that the food color slowly mixed with the cold water while quickly mixed with the hot water.
Explanation:
Even though the water in the glasses is the same, but the difference in their temperature makes them react differently with food colors.
Molecules move faster when they are warmer because they have more thermal energy and slower when they are colder because they have less thermal energy. In this experiment, molecules of warm water are moving faster. Thus the color got mixed up faster. While molecules of cold water are moving slowly, thus the mixing of color is also slow.
6. Drops of water on a coin
Let’s do a cool experiment with the things found in your pocket.
Let’s find out how many drops of water can fit on a coin?
Materials required:
- Few coins
- A dropper and some water
Procedure:
Just fill your dropper with water and carefully drip the drops on your coin—one at a time.
Then count how many drops you can put on one coin until the water overflows.
We were able to get ours up to 20 drops.
Go ahead and record the result for separate trials.
Explanation:
Surface tension and cohesive is the reason you can get so many drops of water on a coin. Cohesion is the sticking of like molecules to one another, as a result of which all the water molecules stick together. Once the water reaches the edge of the penny, a dome shape begins to form, and then the cohesive forces will eventually be overcome by the force of gravity on water molecules. The skin will burst, and all the water will spill off.
