#Heatwave Top tip Top up ice cub trays with HOT water! Bizarrely, it can freeze quicker than cold water. The phenomenon is called the Mpemba effect, after the Tanzanian school boy who discovered it. Best of all 👩‍🔬scientists still aren't sure why it happens. #272sci

Você gosta de #Pizza! A massa de pizza é uma mistura de farinha, sal, fermento (que contém enzimas zimase) e água. A reação que ocorre é: C ₆ H ₁₂ O ₆ → 2C ₂ H ₅ OH + 2CO ₂ (que é a mesma reação da fermentação). As bolhas de gás CO ₂ fazem a massa crescer #272sci

Kat’s #272sci tweets are snippets of interesting chemistry facts - most of which I don’t know! I used to work in the food packaging industry and was always amazed drink can bodies are made from a single disc of aluminum alloy. Metal is so ductile!

Gold (the element, Au) is not always gold (the colour). Nanoparticles (NP) of gold vary from shades of red to purples depending on the size of the particles. The red smears in COVID LFTs is caused by Au-NPs attached to antibodies that, in turn, bind to the virus. #272sci
