Everything around us is made up of a delicate combination of elements and ingredients, each ranging in their complexity. Add or take a bit here or there, and you get soda water instead of water, or infinitely worse, vinegar instead of wine. Add time into the mix and not only is every individual thing in our environment made up of a complex and totally different set of elements: it is all constantly moving and evolving.
So, not to be defeated by our environment, humans have sought out almost every way conceivable to poke, prod and measure just about everything around us.
Measure continues in that tradition, with a useful range of paper instruments for every day use in the home.
