Cut the bottle


First you need to determine the location of the cut. To make it smooth, take a piece of paper and wrap it in a bottle. Align the edges of the leaf to make the line smooth. Then take a felt-tip pen or marker and circle the border around the sheet. Now the sheet can be removed.

Next, you need to take a piece of nichrome wire with a diameter of 0.5 mm, attach one end to a stationary object. For these purposes, I use a black kettlebell. Then we attach one wire from the battery to it.

In order not to get burned, take the wire with pliers. We pull quite a bit so that the wire is aligned.
We apply voltage to the other end of the wire.

It is seen that the wire has become hot. In places of contact with the bottle, the wire does not completely blush, as the bottle removes heat.

We are waiting without moving the wire and holding it in tension for about 30 seconds.
Then quickly remove the wire and spray the place of heating with water. You can also make a bucket of water and dip the bottle there.

You will hear a peculiar click of glass, and the bottle will burst exactly along the line where the nichrome wire passed.

The explanation is simple: during heating a certain place in the glass, internal stress arises. After a sharp cooling, the glass surface cools sharply, and its inner part remains heated. As a result of such a sharp change, microcracks appear, which instantly turn into a split.

    I read it somewhere. In the Civil War, they made glasses from bottles. A crude thread soaked in kerosene was wrapped around a bottle, set on fire, and then in a bucket of water. I tried it, it works.

    Instead of nichrome wire, use copper. Press one turn tightly on the intended place on the bottle (twist with pliers), one end of the wire, or both, leave longer to heat (gas, candle, etc.) for 1-3 minutes. Further into the cold water. The result is similar, only without a kettlebell and battery.

    In the early 1970s it was a passion to arrange various items in bottles. As I cut bottles with a rope dampened with cologne.

    The coil will not heat up. Short circuit at the point of contact.
