Theodore Witte: Caulking Gun

Here’s a story that takes the cake! Legend has it that Theodore Witte of Chilliwack, British Columbia, got his inspiration for the world’s first caulking gun by watching a local baker decorate a cake by squeezing icing out of a piping bag. In 1894 Witte patented his “puttying-tool”, a “simple and inexpensive” ratcheted device that let users apply a sealant without having to touch the stuff with either their hands or a putty knife.
