Stretch Armstrong keeps best at room temperature. Stretch Armstrong is made of latex rubber filled with gelled corn syrup, which allows it to retain shape for a short time before shrinking to its original shape. An estimated 67 different versions from Japan, Germany, Italy, France, Australia, and other countries released Stretch Armstrong variations between 1976 and the 1990s. The last two were filled with a granular solid in place of the viscous liquid found in the other figures. A vacuum pump, which attached to the heads of these figures, removed the air from within, which "froze" the toy in its stretched position.
Rubber cement Rubber cement Rubber cement is an adhesive made from elastic polymers (typically latex) mixed in a solvent such as acetone, hexane, heptane or toluene to keep them fluid enough to be used. Water-based formulae, often stabilised by ammonia, are also available. This makes it part of the class of "drying adhesives": as the solvents quickly evaporate, the "rubber" portion remains behind, forming a strong, yet flexible bond. Often a small percentage of alcohol is added to the mix. Rubber cement is simply a mixture of solid rubber in a volatile solvent that will dissolve it. When the cement is applied,
