Canned Lighter Hot Water Container Rubber Band

Method/Steps

Method 1

Bake a lighter along the can bottle to make it expand with heat and shrink with cold. The cap will loosen after a while, just unscrew it.

Method 2

Prepare a rubber band, put it on the bottle cap, increase friction and twist to open the can.

Method 3

Place the can upside down in warm water. The metal product will expand rapidly when it hits the warm water, forming a gap with the glass surface. Take it out in the water and unscrew it.
