You will need
- - drinking soda;
- - vinegar;
- - bicarbonate of calcium;
- - iodized salt.
Make sodium acetate, gradually mixing in small proportions of baking soda and vinegar. Pour into a glass a pinch of baking soda, pour a bit of vinegar, turn the Cup until just combined. Repeat the operation several times, stir the baking soda slaked with a spoon and let set for 10 minutes in the refrigerator. Ready-made sodium acetate should have a third glass.
Prepare the sodium bicarbonate and iodized salt, these components needed to make solid water balls. With salt you have problems does not arise, it is sold in any supermarket.
Get a small amount of calcium bicarbonate in the home by mixing baking soda and calcium chloride, which buy at the pharmacy. The chemical reaction formula: 2NaHCO3+CaCl2 = 2Ca(HCO3)2 + 2 NaCl.
Bicarbonate of calcium you get from calcium carbonate is ordinary chalk. Dissolve chalk in water. Using the resulting slurry purged carbon dioxide. Gradually the chalk will turn into calcium hydrogen carbonate. Filter the solution and viparita water.
Chilled sodium acetate mix with a quarter Cup of bicarbonate of calcium. Happen violent reaction. Measure out 110 g of iodine soda, add to Cup and stir.
Put the mixture on fire. Cook for 7 minutes, stirring constantly. Make sure that the liquid is not boiling, so adjust the fire in the cooking process.
Pour the liquid into a container. Let cool for 15 minutes at room temperature. Then prove your friends that you have made solid water balls.
Dip your fingers into the container and pulled out a hard ball or scoop a handful of liquid on the palm were a few water balloons. Air obtained the chemical compound turns into a solid. Should lower transparent bulbs in a container as they again become liquid.
