How do I rinse with salt water

Experiments with salt: experiments at home

Whether ground or coarse: with salt you not only add flavor to the soup. The crystals can do a lot more. The workshop presents you with three amazing experiments with the white wonder fabric

Experiment 1: How clean! Money laundering for the home

For the experiment you need:

  • a glass
  • Brandy vinegar
  • Table salt
  • spoon
  • Paper towels
  • Coinage

That's how it works:

1: Fill a glass with that vinegar. Pour in table salt until the bottom is about 0.5 cm high. Stir everything vigorously so that the salt dissolves completely.

2: Lay your dirty Coinage into the solution and take it out after a few minutes. Then rub it dry with the kitchen paper. And? It's sparkling clean!

That happened:

The “dirt” on the coins is mostly oxidized metal. The acid in the salt-vinegar compound, the metal oxide dissolves. The cleaning effect can be seen particularly well with the smaller brown coins, as they have a copper jacket.

But be careful: the salt and vinegar bath not only makes the coins shiny, but also loses a tiny bit of mass every time you rub off the oxidized metal. Not that your clean money has disappeared at some point ...

Experiment 2: How cozy! Atmospheric salt light for the Christmas season

For the experiment you need:

  • Glass
  • water
  • Table salt
  • teaspoon
  • possibly food coloring

That's how it's done:

1: Fill the glass 1 cm high with Table salt. Add enough water so that the solution in the glass is 3 to 4 cm high. If you like, you can add a few drops of food coloring. Stir thoroughly.

2: And now it's time to be patient! Leave everything in a warm, quiet place for a week or two. Don't wiggle the glass so that Crystals can grow up unhindered. Listening in between is of course allowed ...

That happened:

As soon as the water evaporates from the salt solution, the concentration of the salt in the water increases. Since the salt cannot evaporate, it slowly crystallizes out. More and more new crystals attach themselves to the first, already existing ones. One also speaks of Kriswall growth. The place where the glass is and the temperatures there determine the "speed" of evaporation. The faster the water evaporates, the less time there is for orderly, beautiful crystal growth.

Experiment 3: How electrifying! This is how you separate salt and pepper

What you need:

  • Table salt
  • ground pepper
  • balloon
  • Wool sweater

That's how it's done:

1: Scatter salt and pepper. Rub the balloon a couple of times vigorously on the woolen fabric.

2: Now guide the balloon slowly just over the Spiceswithout touching it. The pepper jumps on the balloon and sticks there.

That happened:

Due to the friction on the fabric, the balloon becomes electrostatic charge. This makes it really attractive to the spices. Since peppers are lighter than crumbs of salt, they are the first to be attracted to the balloon and stick to it. After a while the charge will decrease again. You can simply freshen it up by rubbing it again.
