In the following process you're going to learn how to cut a bottle of wine with only a string and fire. This can be done because the temperature in a certain part of the bottle is heated more than the rest, and when the bottle is placed in water, the bottle splits. To be able to do this you need to be very careful as we are using fire and dealing with glass too, that's why we need to be careful not to cut ourselves.
