Man, I wish I could have snuck in and placed a heavy duty humidifier right next to the evaporator....and then removed it before you arrived in the morning. That might have made for some hilarious results.
That would've done the trick alright

Better yet, get a big drum of olive oil, proper it under, would have frozen it all up, and when you removed the bucket it would be incredibly wierd looking as the outside started to melt!
And made for one hell of a mess

OMG, how did i miss this thread .... its damn cold!
Yep, and it'll be even colder when I put it in a vacuum (I'm guessing -145C under normal ambient conditions in our shop).
