Betagel (βゲル in Japanese) is a high-tech Japanese invention which utilizes gel and silicone to absorb violent shocks. Japanese researchers developed {{Interlanguage link multi|Alphagel|fr}} for use as a shock absorption material for earthquakes prior to creating the Betagel, using a classification system with greek letters "α, β,..."). "α"gel resulted in the creation of the "β"gel, which proved seven times more effective. An egg can be dropped from a maximum height of 22 metres to a 300 mm² square plate of Betagel without breaking. Alphagel managed this only up to 3 metres.{{cn|date=February 2019}} External links
