Many had unpleasant situations when a full glass jar was broken due to an accidental blow on a hard or sharp object and all the contents spilled onto the ground. There is a fairly effective method of protecting it.

What to prepare


Depending on the diameter of the cans, plastic bottles of the appropriate size should be prepared. To protect a three-liter jar, a five-liter plastic bottle is excellent; a 0.75-liter glass jar is the same diameter as a one and a half liter bottle. Additionally, you need a building hair dryer, you can use an ordinary household with a power of 2 kW. Plastic is cut with an assembly knife, the edges are fixed with scissors.
