Physical and chemical experiments at home: feel like a magician!

The great thing is that alldescribed experiments at home, and watching them is really exciting, even when you know 100% what the result will be. Well, if some of these experiments you demonstrate to your child, then for a long time you will remain in his imagination as a kind of fairy-tale creature possessing ancient magic. Are you ready? Then rushed!

Experience # 1. Flying tea bags

What you need: matches, scissors, tea bags.

How to make: tea bags need to be opened, cut off the label with a label, and pour out tea bags from pouches. Then it remains only to put the empty bags on the table (in the form of factory pipes) and set them on fire.

What happens: if you let the bags burn to almostend, you can see how warm air entrains the burning packets up. If you are just starting to do experiments at home, this experiment will be an excellent choice, because it is very easy to conduct it, and the flying remains of sachets look even beautiful in their own way.

Experience number 2. Glowing patissons and cucumbers

What you need: salted and fresh cucumbers, patissons, wires, access to 220 V network, copper wire.

How to make: first you need to attach a copperwire to the wire. Next, you need to stick the tips of the wire into a fresh cucumber and connect the wire to the network. Then change the fresh cucumber to the patisson and do the same with it. Now you need to repeat all these operations with the pickled cucumber.

What happens: In the case of a fresh cucumber you will see nearformed holes a bubbling juice and a light smoke emanating from the cucumber. But as soon as you change the cucumber to the patisson, it will begin to glow from the inside. The salted cucumber will not only glow, but also move. Such experiments at home prove that the amount of salt in the object is directly proportional to its electrical conductivity.

Experience No. 3. How to cut with scissors ... glass

What you need: an aquarium filled with water, scissors and thin glass.

How to make: a sheet of thin glass must be immersed in an aquarium with water, holding it with one hand. Then lower the hand with scissors into the water and begin to slowly cut the glass.

What happens: in the water due to the capillary effect, glassbecomes much more malleable, and therefore it is possible to cut it very simply, with only a small effort. And the line of the cut will turn out very neat, not "torn". However, this experiment does not end at home.

Experience No. 4. Heating of iodine and starch

What you need: burner, test tube, starch, water, iodine.

How to make: this experience is often included in various collectionssuch as "Chemical experiments at home for children." Watching the reaction to the students will not only be interesting, but also useful. In a test tube you need to pour a pinch of starch, and then add water. Then add a little iodine, light the burner and gently heat the mixture. Then the test tube should be cooled by placing it in a glass with cold water.

What happens: in the heated state, the solution loses its dark blue color, but upon cooling it again returns it.

These and many other interesting experiences at home you can perform at any time. Experiment, try, but most importantly - do not forget about your own safety!
