Gingerbread Inert Gas Hood

Gingerbread houses are fun to build, but by the time you finish your masterpieces, they usually have gone stale. Where is the fun in that?

I propose a collapsable inert gas flow hood that can be set up each holiday on the kitchen table. Basically an acrylic box, with two holes for your hands and rubber gaskets around the holes. Attached to the back of the unit is a small canister of a compressed inert gas, say nitrogen or argon. There is also a small fan inside the box to provide circulation.

When you've got everything you need to make your gingerbread masterpiece, you simply load the materials into the hood, flood the box with the inert gas, and stick your hands through the holes. Since this is not a chemistry or biohazard setup, the holes don't require gloves attached. It doesn't have to be a perfect seal. You just want to be able to work with the foodstuffs in an envelope of gas that excludes oxygen. The fan will circulate the atmosphere enough to provide evaporation for the construction icing (mostly egg whites and sugar).

When finished, you can transfer your house to a smaller clear plastic cube and fill that with the same inert gas for display purposes. You can also reach in and eat it if you like. Keep away from Hansel and Gretel.
