5 physical experiments that can affect everyone

  • Dec 26, 2019

You can conduct physical experiments in the field of thermodynamics, dynamics, optics, and electricity only to the items found in your own kitchen!

Scientific experiments - a great way to introduce children and all of us with the fundamental scientific principles. Here are some great physical projects that you can do at home.

For any of these experiments adult should monitor their children always wear protective goggles and working with fire to have a fire extinguisher.

5. Amaze your friends with fireproof balloon

For this experiment, all you need is an air balloon and a candle. Fill the balloon by three-quarters water and blow out to get some air.

Light the candle, then slowly lower the balloon over her. You will see that the balloon will not burst!

This is due to the incredible ability of water to absorb heat. The water in the balloon dissipates heat generated by the candle and holds latex bead from heating sufficient to melt the bead. But when the water in the ball can no longer absorb heat candles, ball burst, and you are likely to get wet a little.

I enclose a video illustrating this experiment.

4. lava lamp

Find in your kitchen: a bottle of vegetable oil, food coloring, a little salt and a large glass jar.

Fill the glass jar 2/3 water and the remainder vegetable oil. Add food coloring, then slowly pour one teaspoon of salt. Watch as the beautiful colored oil balls gently fall to the bottom of the banks.

First, the oil will remain in the upper portion of the container, because oil is lighter than water. The key to the fact that the oil falls to the bottom, is a salt, it communicates with the oil, making it heavier than water. However, once the salt dissolves in the water, oil will rise again to the top of the container. Voila!

3. Grow few crystals

This classic experiment takes a few days, but it's worth it.

You will need distilled water, salt and a piece of wire and a glass container (the bank). First heat the distilled water to just below the boiling point. Fill the glass container half with hot water. Add a lot of salt in the water and mix well.

Tie thread a piece of wire to a wooden stick and push the wire into the vessel (see. video). Place the container in a warm place and wait. After a few days, you should see a spectacular salt crystals are formed on a loop of wire.

This experiment works because of the changes in water temperature and solubility, the ability to dissolve the salt. On cooling, water solubility of the salt in the mixture is reduced and the salt deposited on the wire to form crystals.

2. Create a catapult with popsicle stick on the child

To build this mini-catapult, you will need at least 10 large popsicle sticks from, a bunch of rubber bands, scissors and a few caps from bottles as cannonballs.

You can also tie a plastic spoon with a rubber band to the top of a stick to make a "container" for cannonballs. Bailey exactly crumble! :)

1. Make elemental prism

You can make only elementary prism with distilled water and a transparent gelatin. Put a packet of gelatin in a saucepan and add only half the amount of water specified in the instructions to the gelatin package.

Place the pot on the stove and when the pan heats up, gently stir the gelatin to dissolve it. After the gelatin was dissolved, the mixture was put in a small container and leave for 30 minutes to cool.

Cut the congealed gelatin into squares or prisms that make up half the diagonal of a square or rectangle. Route the torch through the gelatin to see the light, split into its spectral colors. You can also spend a laser pointer through the gelatin to see the light bends.
