To create the enclosure of choice – a crème filled sandwich of wood slices using wildly unpredictable spray foam insulation – one must follow the below recipe:  

PREP

Put on full hazmat suit, complete with gloves, safety glasses, and mask. / Activate Component A and Component B pressure cylinders which, when combined, will create the fluffy foam filling we know and love. / Spray a small amount of foam into a waste bin to ensure proper mixture of chemicals. / Have nail gun, mallet, and replacement nozzles at the ready.  

SE 1 - BOTTOM

Use nail gun to anchor first slice of the sequence. / Watch BC (name of co-cook) administer the spray foam. / Wait and determine expansion coefficient of foam. / Proceed to next slice.  

SE 2 - BOTTOM

Secure next slice into position with pre-marked overlap depth. / Use nail gun to anchor slice into sequence. / Watch BC administer spray foam, this time a little more generously. / Notice that foam expansion quickly accelerates. / Use mallet to contain and spread foam. / Observe that it is too late and the fluffy foam is now a rigid cloud. / Inform BC that the foam sandwich is bursting at the seams, altering the intended interior geometry. / Deactivate spray foam canisters. / Use hand saw to slice off excess foam and secure slices back into place. / Reactivate spray foam canisters, reignite chemical mixture, and secure new nozzle. / Proceed to next slice.  

SE 3 - BOTTOM

Secure next slice into position. / Use nail gun to anchor slice into sequence. / Watch BC administer spray foam. / Notify BC that fluffy clouds do not seem to be forming. / Confirm Component B is running low. / Switch to handheld spray foam cans. / Register the new expansion coefficient and proceed.
