I know that lots of reptiles go into brumation either when it is very hot or very cold. Most reptiles from north america go into brumation during the winter. As an example alligators form alligator holes and all except a breathing space for the alligator freezes over. The alligator is in cold water and breathing cold air so it goes into brumation to survive the cold. So if my future children or I get a reptile as a pet and I want the reptile to go into brumation during the winter so that I have a low maintenance period and can focus on other things would I need to do this: 1) Take a waterproof and watertight box and put the reptile inside. 2) Put the warmer box inside a bigger waterproof box to use as a cooler. 3) Put ice in the box and let the smaller box cool down. 4) Close the box of ice and check on the small box temperature regularly to see if I need to add more ice(The best way to do that would be to listen for activity from the reptile). and 5) wait until winter is over and gradually warm it up so that the reptile can wake up naturally.
