Our Flask Inventory Boileth Over
So we're pricing these borosilicate boiling flasks to move quickly. We've got (3) sizes, all with slightly flattened bottoms, each with a single, discreet, capacity mark in white. While the actual physical size can vary slightly, the volume remains the same. The 1000ml flask is 9-5/8" tall OA x 5-5/8" dia with a 1-5/16" ID mouth, and a lip. Takes a #7 rubber stopper. The 500ml flask is 6-7/8" tall OA x 4-1/8" dia with a 1-3/16" ID mouth, and a lip. Takes a #6-1/2 rubber stopper, but a #7 will work. The 250ml flask is 6-1/8" tall OA x 3-3/8" dia with a 1-1/32" ID mouth, and a lip. Takes a #5-1/2 rubber stopper, but a #6 will do the job.

The Mother Of All Fresnel Lenses
It came from either outer space, or a projection TV. Our largest Fresnel lens measures 49-1/8" x 37-1/8" x 1/16" or 1/8" thick, with a 42" focal length. Build your own lighthouse or projection TV, teach optical properties to students, or just turn your 21-inch model into one with a tavern-size picture. Held in the sun, the lens will concentrate rays enough to cook eggs or torch lumber. And, under adult supervision in the parking lot, employees of a certain un-named scientific and surplus purveyor actually melted pennies in seconds. Extremely cool and done strictly, we assure you, to determine the lens's focal length. Do not, we shouldn't have to remind you, store this puppy in direct sunlight. Or let the underage or under-mature sneak it into the sunlight.

This Little Piggy...
holds your keys, goes oink, oink, and lights your path all the way home. Which ain't bad for a cute, 2" long, 2-buck pink-plastic porker. Push the button on his head and (2) white LEDs shine out of his nose (makes a nice change, we think) while he emits a very pig-like oink or two. Comes complete with a 1" chain, clasp-ring, and (3) internal button cell batteries.
