Do you know how to make ice cylinders without a freezer? Simple! Just leave your garden hose outside in freezing temperatures overnight, and remember to coil it up!
The next morning, uncoil the hose and turn on the water. There you will get a free pile of cylindrical ice cubes spit out of the hose.
Unfortunately, as you can guess this ‘homemade’ ice cylinder maker doesn’t work in summer or in warm areas. If you’re a kid and want to produce ice cylinders remember to ask your parents first.
