Quite a few interesting condiment containers are on the market, but I think the Natwerks Mounting Sauces are probably the most interesting and most entertaining thus far.
The Natwerks Mounting Sauces feature your basic condiments in the form of a caulk gun. This pistol-esque contraption helps seal joints or seams in various structures and certain types of piping, but in this case, the Natwerks took this construction tool and applied it to everyday culinary uses. Instead of spreading or squeezing ketchup and mustard into a burger, you now have the fun of applying it with a caulk gun instead. The design presents a fun and clean way to get condiments into your food without the stress and mess of traditional squeeze bottles.
