What is Diatomaceous Earth?
Have you noticed the popularity of diatomaceous earth coasters and foot pads in recent years? They are said to absorb water instantly and are made from natural diatomaceous earth, making them eco-friendly. But what exactly is diatomaceous earth? Why does it have such effects? Does diatomaceous earth have any other functions? \Let's Play Science\ will introduce you to diatomaceous earth and guide you in making your own diatomaceous earth coaster and air freshener. What are you waiting for? Sign up now!

The first "Chengda Science and Education Center-Come and go to Da Play Science" activity in the new semester appeared strongly!nToday, Professor Li Enrui, the Department of Science and Technology of Cheng Dadi, will be invited to share with you, "What soil is the diatom soil?", Teacher Li started with simple experiments to let big friends and children prepare diatom soil and gypsum (and secret spices and pigments) themselves. Make the fragrant "scentstone" and "diatom cushion", and then explain the differences and uses of gypsum powder and diatom powder (which one is slippery, which one is a bit small? )!nIn the Classroom and Science and Education Center, there is a team of college student volunteers led by Professor Xu Ruirong (former Director of the Center) to introduce a variety of interesting popular science experiments and instruments, so that everyone can learn interesting science from hands -on. Knowledge!nI believe everyone has a full afternoon full of scientific knowledge and happiness! Please tell you, invite everyone to be a guy together, and participate in the science and education center's "Come and go to play a big play science" (and other activities!), Please also give us more advice and suggestions to let us continue to improve! Please also pay more attention to our fan page and continue to register!
