After a bit of thinking, Jen decided that the best thing she could make would be a portable freezer. A portable freezer which is used like a gun.
Being a resident of the United States, she went to the closet and took the pistol from the top shelf. Its for self protection! Probably. She took the ammo out and proceeded to bend a glass cup into a curved shape which could also fit into where the magazine went. It took a couple tries and by the end the gaslit stove was covered in glass. Its a good thing Jen was wearing her ceramic tiles!
After putting the curved tube into the pistol, Jen took the part that took heat out of things (htpmp) from the freezer and put it into the gun ((pistol * tube) + htpmp). Then she filled the tube with water and pulled the trigger on an unsuspecting glass of water. As she held down the trigger, the water in the tube started emitting steam while the water in the glass began to freeze. Wanting the process to go faster, she took the htpmp from the fridge and put it into the gun ((pistol * tube) + 2htpmp). With her new gun, Jen was able to freeze the whole glass in 2 minutes.
Wow.
