Welcome to the latest Ci newsletter, in which we look at the polymers that make up your clothes (and what makes them crease), the science behind the ice creams keeping us cool during heatwaves, and more!

We’re in the middle of a heatwave in the UK at the moment, so it’s pretty apt that Ice Cream Day is this coming Sunday when the heat is meant to peak. As well as this graphic, which looks at the structure of ice cream and its components, there’s also this edition of Periodic Graphics which looks at how different frozen desserts compare.
Whoosh bottle: What happens at different temperatures?
The whoosh bottle is a classic chemistry demonstration, but what happens when you carry it out at different temperatures? That’s what Tom Kuntzleman wondered, and his subsequent blog post is an interesting exploration of the effects with some unexpected conclusions.
Fruity national days
There are a couple of fruit-themed national days coming up, with cherries on Saturday and mangos next Friday. Of course, there are graphics for that! This graphic on cherries explores their colour and why their pits are poisonous, while this one on mangos looks at what they have in common with poison ivy.
At the end of the International Year of the Periodic Table in 2019, Clare Wilkes decided to embark on a project to make a monochrome periodic table formed from individual blackwork patterns for each element. Two and a half years later, her project is complete, and you can view the full table, as well as the individual patterns for each element, on her website. It’s fun to browse through and see if you can work out what’s depicted for each element – and why!
That’s all for this fortnight. You may have noticed (or maybe you didn’t!) that I took an accidental fortnight off two weeks ago, as I just had too much stuff going on. Normal service should now resume! As always, get in touch if you’ve got any feedback or suggestions.
