The detail of intricate branches and the natural beauty of fractals are displayed in wondrous creations created by powerful particle accelerators and an electron beam of 3Ð5 million electron volts. These Lichtenberg Figures are fern-like branching patterns permanently captured within crystal clear acrylic plastic. Each is uniquely created by carefully trapping and discharging multi-million volt regions of electrical charge inside acrylic. The complex, permanent figures are created when the trapped charge suddenly escapes in a brief, lightning-like discharge, leaving behind permanent 'fossilized' tree-like branching chains of microscopic fractures. Displayed on LED light boxes, sold separately, the sculptures reflect light like microscopic mirrors, highlighting the awesome aesthetic of dielectric physics. Lichtenberg one of a kind creations are available in three different sizes, so you can choose the one best suited for your home or office display! See less

The earliest barometers were simple glass bulbs with a spout that helped ancient seaman predict storms. Water moving up the spout means low pressure with potentially stormy conditions, while high pressure pushes the water down to the bottom of the spout. This style of barometer is just as effective today, and provides a decorative method for predicting weather via changes in air pressure. When good weather approaches, the liquid in the ball is pushed down the spout. When bad weather is on the way, the liquid rises. If liquid spills out the top, it's time to run to high ground!

Customer Reviews Overall Rating: and share your thoughts with other customers Sort Reviews: Newest | Oldest | Highest Rating | Lowest Rating - Saturday, September 27, 2008 Excellent for lectures Reviewed By: Jim Thomas (Port Jefferson, NY) This is an excellent laser pointer and it has terrific battery life. It is a class IIIa laser which is perfect for lecturing in small and medium sized lecture halls. A green laser is better for very large auditoriums but a green laser is also very inefficient and has a very short battery life. This laser pointer is red and is ideal for class rooms and lecturing before 100 people, or more. The batteries will last for years under normal lecture hall use. - Friday, September 21, 2007 Laser Pointer Reviewed By: Wallace Rust (Rochester, New York) This is a very nice laser pointer with a bright and small red spot.

The Second Law of Thermodynamics Embodied in a Glass Bird These "Dippy Birds" have been around for years, and you can't fool us - you've always wanted one. Now's your chance! But do you understand how it works? Do you get the complex relationship between chemistry and physics that makes this simple heat engine operate? Is it a perpetual motion machine, or is it something more than that? Well, the answer is it's more than that. The Second Law of Thermodynamics states (paraphrased) that energy can neither be created nor destroyed in a closed system. So how does that relate to our little glass birdie here? The goop in his butt is methylene chloride has a very low boiling point, and therefore evaporates quickly. At room temperature, one or two degrees temperature difference causes the bright red chemical to climb to his head. Suddenly topheavy, he falls over. The felt head, soaked in the water from the cup, cools the methylene chloride, and it drains back to the bottom. The bird rights... See less
