But wait, how can you ensure that your handiwork, and your patient, will survive until the big night? By freezing them solid in a block of ice!

First, we prepare some cryogenic fluid by boiling a big pot of water. Boiled water freezes clearer than unboiled water, and you get to call it "cryogenic fluid" when you're done. Pour maybe an inch of cryogenic fluid into your pumpkin-sized freezer-safe container, and freeze it.

While we wait for bottom to freeze, we will prepare the pumpkin for its preservation. Because pumpkins float, cover the bottom of your pumpkin with most of or all of a roll of pennies. Be careful that you don't disrupt the artificial brain if you opted to use a switch in yours.

Next, make a small collection of perhaps a half-dozen cucurbita staples. These are short pieces of wire or perhaps paperclip, formed into an angular "U" shape with pliers. Use them to secure the stem to the main pumpkin so that it does not float, to fix the artificial brain in place, and to rein in any stray wires. It will probably be necessary to use pliers to insert them in the pumpkin as well.

When the cryogenic fluid in your pumpkin-sized container is frozen, place the pumpkin in it away from the sides and pour in enough cryogenic fluid to submerge it. Even lukewarm cryogenic fluid will begin to melt the already frozen layer, so be sure freeze the container quickly.
