without hurting them?Here are the three creative steps that
the writer took to trap the snakes by cooling them and making them sleepy
so she could catch them.
Step 1: She bought a stainless steel ice cream maker and froze the bowl. She added ice cubes to the top of the bowl to keep it cold. She placed it over the snakes'habitat during the day so that the snakes would become sleepy and could be easily caught.

active?Snakes do not have a way of keeping warm in their bodies. They get warmth from the sun and become more active at this time. When the sun goes down at night they cool down and become less active. So extra cooling to the snake would make them even less active and easier to catch. you are able to prove that you are
the first person to make the invention;

you can make money if you sell your
invention to others.Discuss with your partner what the
