Question: The unusual tea kettle shown in my photograph was donated to the nonprofit thrift shop I manage. Information about the item, including value, will be appreciated. - P.B., Somers Point

Answer: The generous donation, a Kamenstein Rocket tea kettle, was patented by M. Kamenstein Inc. of Elmsford, N.Y., in 1999. Just a decade after the company began producing its Rocket kettle, the novelty kitchen item has become a coveted contemporary collectible.

Rocket, one of the models featured in Kamenstein's Motion Kettles collection, is made of highly polished stainless steel and holds 2 1/2 quarts of water. Located at its top is a rotating ring powered by steam produced when water boils inside the pot. As the ring turns on its ball-bearing base, a pair of attached rockets circle the tea kettle. In addition to providing amusement, the kettle's revolving rockets signal users that water is boiling.

Originally available as a premium offered by Gevalia and other coffee companies, the Rocket sold for $70 to $80. However, because the tea kettle is no longer manufactured, demand for the scarce, popular model has driven prices sky-high. During the past year, folks who collect Kamenstein motion kettles have spent $300 to $700 to own a Rocket, based on overall condition and the presence of an original spout cap.

Question: I recently found a little silver shoe that looks like a child's old-fashioned boot. Raised printing on it reads, "Three Feet-in-One Shoe." A small tab is attached to something inside the shoe, but the tab is stuck. Can you tell me anything about my little discovery? - W.N., Wildwood Crest

Answer: The item you have described is one of a series of five silver-plated, figural tape measures made in America during the early 1900s. Produced for use by seamstresses, the whimsical sewing accessories house a yard-long, tabbed tape that can be pulled out and retracts after use.

Collectors whose specialty is sewing accessories are paying $80 to $95 for a Three Feet-in-One Shoe tape measure that operates perfectly and shows little wear. Because your tape measure's mechanism is jammed, it is valued at $10 to $15.
