Paradox 10 Minute Egg Timer / Hourglass That is the Paradox! The sand flows from bottom to top ? and that somehow makes the time different? While they may not cause time to flow backwards, they are a paradox. Available your choice of the following colors: Light Blue, Light Green, Light Purple, Light Orange or Light Pink Hand made in Germany! Each individual hourglass is filled and sealed by hand. The liquid which is used is made from natural and non-toxic ingredients. For the coloring, a color master is specially instructed to watch over the consistently high quality of the color mixture and the careful coloration of the pellets. That is the only way to achieve the intense and brilliant color effect. Even the containers are made from first-class quality plastic so no discolorations impair the visibility. The running times of the individual models are approximations: the viscosity of liquids depends strongly on the ambient temperature and the pellets have different diameters and, depending on the color, also different weights. For technical reasons there are also small differences in the filling capacity. Keep your daily tasks on track with this sleek timer! The Paradox Liquid Egg Timer indicates the time to cook your egg just the way you want. Accurate calculation of an egg? No way! The perfect breakfast egg requires much more than simple math: appearance, color, timing, relaxation, entertainment and even a little bit of anticipation. To put it in a nutshell: you need a PARADOX Egg timer! The circle a geometrical perfect figure? Forget it! The egg as a paradoxical counter draft is much more exciting. Offering more inspiration. Whats happening inside of it? As the time flows upwards in the timer? In your color? Paradox - a somewhat different kind of time measurement!
