By connecting a regular glass jar with a plastic egg-box you can get a more reliable container. Rugged cans are simply indispensable during transport or when capacity is used as a storage system. Shrinking will help to turn the usual jar into an unkillable one.
How to "put" the bank without problems
Heat shrinking can be achieved in different ways. In any case, first you need to pick up the correct size of the bottle and cut it. The presence of a building hair dryer in the house will greatly facilitate the task.
To begin with, we place the jar inside the egg caps.
We start to blow the jar with warm air. We do this gradually to allow the air between the can and the baklaga to exit.
Turning over the bank, we continue to blow.
Ensure full adherence of plastic in the bottom area will not work.
Cutting off the excess plastic, we carry out the final blowing.
In a similar way can be strengthened cans of any capacity and even bottles.
There is another way to "dress" the bank. This can be done by lowering the jar immersed in an egg-pot in a pot of boiling water. The jar for this is better to preheat to avoid cracking due to temperature differences.
