MATHS GEAR IS TEMPORARILY CLOSEDUK residents have been asked by the government to stay in their homes because of COVID-19. We won't be able to fulfill orders until the curfew is lifted. Sorry for the inconvenience.
With the Drinkulator, you can drink and calculate at the same time, or 'drinkulate' as the cool mathematicians are saying. Use your drinking glass to add, multiply, subtract and divide.
The Drinkulator works using the curve of a depressed cubic equation - a cubic equation with no squared term. When a straight line crosses the curve, they intersect at three points. The scale on the curve allows you to use two points to work out the third. Simply orient your glass so the level of liquid forms a straight line across two of the values you want to calculate with, and it'll also pass through the third!
The Drinkulator is a one pint (568ml) glass mason jar, complete with sturdy handle. Not suitable for hot beverages.
