Invented by Eddy Goldfarb and released by Mattel in the 1960s, Vac.U.Form was based on the industrial vacuum forming process.
A rectangular sheet of coloured plastic was clamped in a holder and heated over a metal plate.
When the plastic was soft, the holder was swung around over a mould of the object to be formed. Quickly and repeatedly pressing down on a spring-loaded handle on the side of the unit created a vacuum, sucking the plastic down over the mould and shaping it to fit.
When the plastic cooled, it solidified, creating an impression of the item.
Various moulds came with the kit, and several expansion kits were available, although almost any small object that could withstand the temperature of the heated plastic sheet for a few seconds could be used as a mould.
