Because of the large size of 40MM dice, they're more likely to be produced in lighter material wooden or foam. And we can also do the size in plastic material--which will be a heavy cube. Those polyhedral dices like 50-sides, 60-sides one will tend to use such big size to get numbers clearly showed.
With all the sizes of dice available, don't know which size you need? Is a 12MM Dice big enough to easily game with? Just how large is a 25mm dice compared to other game components? Take a look below at our examples of all the common dice dimensions to find out!

Taizhou Junior High School Students Successfully Challenge the World's Highest Precision Titrator
Taizhou Junior High School Students Successfully Challenge the World's Highest Precision Titrator At the 23rd Zhejiang Youth Science and Technology Innovation Contest, which ended recently, Zhang Yiming, a student of Taizhou Junior High School, challenged the world's most advanced electronic titrator. The electronic titrator produced can be accurate to one hundredth of a milliliter. At the scene of the competition, after high-precision balance measurement, the judges were surprised to see that Zhang Yiming's titrator can be accurate to one thousandth of a milliliter. This invention of a thousandth precision titrator was finally awarded the first prize of the competition with the highest score. This is also the seventh consecutive year that Taizhou Junior High School has won the first prize of the Zhejiang Youth Science and Technology Innovation Competition. The micrometer and infusion set Zhang Yiming's creativity came from a chemistry classroom experiment. During the use of the titrator, he found that the surface of the liquid in the general test tube was concave, and the scale on the test tube did not accurately show the liquid volume. After many classroom experiments, he proposed to Lu Nengxiao, the tutor responsible for students' innovative inventions, that he wanted to invent a more precise titrator. After reading the professional materials, Teacher Lu Nengxiao believed that this idea has certain practical value and is also feasible. At that time, Teacher Lu gave Zhang Yiming an assignment to make a preliminary design plan and design drawings in writing. Inventions are not as simple as imagined. In the constant revision of the design scheme, Zhang Yiming found himself in a dilemma. "I can only give students guidance and tips, such as the use of materials and replacement of appliances. The invention depends on themselves." Lu Nengxiao believes that students' creative thinking can only be brought into play through continuous thinking and self-exploration. One day, in a normal physics class, a physics teacher used a micrometer to make a measurement experiment. Zhang Yiming looked at it, his eyes were bright, and he found the answer: a micrometer plus an infusion set. By squeezing through the infusion set, the water surface of the test tube is closer to the horizontal state, and the micrometer makes the measurement more accurate. Zhang Yiming succeeded. It's fun and useful. Zhang Yiming is not inventing alone, but a large group of students working together. The students of the school have obtained more than 30 inventions and obtained national patents. In the chat room, the reporter followed Teacher Lu to the school laboratory. Various instruments, processing tools and inventions left by students occupied most of the room. "This is a small generator that can freely control the amount of electricity generated." Lu Nengxiao pointed to a small generator in the corner. The small generator sold on the market can only output a fixed amount of power, but this small generator You can freely control the amount of electricity generated. As much as you need, he can generate as much electricity as possible. The fuel consumption is about 50% less than that of ordinary generators.
