Guess this object and win!
Rocky’s been busy lifting large boulders, and then seeking medical assistance for the consequences of lifting large boulders. He apologizes for his recent blog silence, and offers another “Guess this object” contest as a goodwill gesture to his loyal readers. As always, the reader who correctly guesses the object will receive a unique prize of dubious monetary value.
Hint: The dimensions are 30cm x 30cm x 30cm. The yellow material is chamois (genuine). Inside of the object is a flashlight and a Poland Spring water bottle filled with 50% anti-freeze (Prestone) and 50% water. A piece of asphalt shingle is on the top of the object. And the stripes are “designer” duct tape.
[Disclosure: Rocky rarely uses duct tape with designer colors. As Trophy Wife will attest, he's strictly a grey-sort-of-guy.]

shoeshine box
Sorry, that’s incorrect. Rocky presumes the chamois misled this otherwise astute market savant — who is well-known for his crystal balls….
Is it a trumpet wrapped in a cocoon of foam and cardboard? Or a fish tank…
There is some foam involved. However, no fish or Lepidopteras are involved. Sorry.
A mouse trap.
Hi Solfest. Long time no speak. Sorry, chap. It’s not a mousetrap in either the literal nor Agatha Christie meaning. (It’s 30cm x 30cm x 30cm, and it’s not a rat trap either.)
A house roof snow pressure thickness indicator. When the flashlight turns on it is time for Rocky to grab a shovel before the roof collapses.
Nice guess, Pittbull. Your guess is the “warmest” so far, but incorrect. Sorry!
A cooler for chilling beer whilst fishing?
Great idea. Perhaps that will be the application in its next life. But sorry (loud buzz sound heard on 1970′s game shows), you are incorrect.
Is it a yield sign?
Dylan, Rocky suggests that you cut back on your psychedelic drug use. .
The Unabomber was innocent.
Rocky has valuable wood objects (e.g. antiques or floors) which he fondles with chamois cloth moistened with a 50/50 MonoEthyleneglycol & water solution. This is an ingenious and relatively cheap way to prevent rot and fungi in wood (it also works as a treatment after the fact). Rocky finds really helpful to use a flashlight while applying it.
I assume back pain doesn’t make it impossible to type. Please post more often.
David: Thank you for your creative submission. Rocky’s secret sauce is actually 1/3 Linseed Oil, 1/3 White Vinegar, 1/3 Turpentine. He learned this trick from a famous luthier — and it’s suitable for both furniture, floors, and Stradivarius violins. Unfortunately, your guess is incorrect. But thank you for commenting!
Does this contest ever end?
I haven’t slept in 2 weeks.
