Prince Rupert's drops have remained a scientific curiosity for nearly 400 years due to two unusual mechanical properties: [4] when the tail is snipped, the drop disintegrates explosively into powder, whereas the bulbous head can withstand compressive forces of up to 664,300 newtons (67,740 kg f).
Slender glass lizard (Ophisaurus attenuatus)Ophisaurus (from the Greek 'snake-lizard') is a genus of superficially snake-like legless lizards in the subfamily Anguinae.Known as joint snakes, glass snakes, or glass lizards, they are so-named because their tails are easily broken; like many lizards, they have the ability to deter predation by dropping off part of the tail, which can break into ...
Anguinae is a subfamily of legless lizards in the family Anguidae, commonly called glass lizards, glass snakes or slow worms. The first two names come from the fact their tails easily break or snap off. Members of Anguinae are native to North America, Europe, Asia, and North Africa.
Spontaneous glass breakage is a phenomenon by which tempered glass may spontaneously break without any apparent reason. The most common causes are: [13] [14] Internal defects within the glass such as nickel sulfide inclusions. Nickel sulfide defects can cause spontaneous breakage of tempered glass years after its manufacturing. [15]
Annealing is a process of slowly cooling hot glass objects after they have been formed, to relieve residual internal stresses introduced during manufacture. Especially for smaller, simpler objects, annealing may be incidental to the process of manufacture, but in larger or more complex products it commonly demands a special process of annealing in a temperature-controlled kiln known as a lehr.

Similar stylets on the legs are absent in family Meinertellidae. [14] They have one or two pairs of eversible membranous vesicles on the underside of abdominal segments 1 to 7, which are used to absorb water and assisting with molting. [15] There are nine pairs of spiracles; two pairs on the thorax, and seven pairs on abdominal segments 2 to 8 ...
A 4-year-old accidentally knocked over and shattered a 3,500-year-old Bronze Age jar during a visit to the Hecht Museum at the University of Haifa in Israel on Friday.. The museum said the ...
The eastern glass lizard (Ophisaurus ventralis) is a species of legless lizard in the family Anguidae and the longest and heaviest species of glass lizards in the genus Ophisaurus, [5] [failed verification] endemic to the Southeastern United States. The streamlined, legless species is often confused with snakes.
