Ram pumps are probably my most requested topic. But getting a transparent one working was really hard. When I understood them a lot better.

Hooded Seals are amazing!

💾

I’ve been working on an idea for about a year, and it’s finally ready to show you. Maybe you’ve heard of this amazing animal called the Hooded Seal.

The male has an incredible mating display where it inflates a giant red membrane out of its left nostril! When I told my kids about it, they thought it was the most amazing thing they had ever heard of.

Ever since, I’ve been trying to turn the hooded seal into a plushie with an actual inflating red nose bubble. Well I’ve finally navigated all the design constraints that come with soft toy manufacturing and perfected all the little details, and I’m proud to say it’s ready for preorder!

I know this isn’t my typical subject matter but I’m a huge fan of biology behind the scenes, and this has been a bit of a passion project. So I hope you’ll take a look and consider placing an order.

Get one for your kids, or stick one on your coffee table, it’s a brilliant conversation starter! https://shop.stevemould.com/

More information on hooded seals and efforts to protect them:

Hooded seals live far up north in the Arctic. The sea ice there is disappearing faster than almost anywhere else on Earth, which is why they are now classified as endangered.

When you add this plushie to your cart, you have the option to include a donation of 5%, 10% or 25%, or you can skip it. All donations go straight to the 90 North Foundation, a charity campaigning to turn the Central Arctic Ocean (about 2.8 million square kilometres of water around the North Pole) into a proper marine reserve. It's the fastest-warming, fastest-acidifying ocean on the planet, and as the ice retreats, it's opening up to fishing boats, cargo ships and mining vessels that couldn't get there before.

90 North works with real scientists to make the case for protecting it before it's too late.

Counterflow heat exchangers are really counterintuitive because they can swap the temperature of two liquids.

The Anti Trampoline Effect

💾

Click this link https://www.hensonshaving.com/stevemould and use the
code stevemould to receive 100 free blades with the purchase of your AL13 razor

When you combine a bouncy surface with a bouncy ball, you might kill the bounce! You have to tune their vibrations!

Dr Andy Wright at the University of St Andrews contacted me after watching the atomic trampoline video (https://youtu.be/QpuCtzdvix4) because some of the questions I had in the video had been answered by a couple of final year projects he had run (completed by undergraduates Connor Richardson and Sam Edwards). They found they could tune their model of a golf ball and club to give a perfect bounce or a rubbish bounce. Andy kindly shared the simulation code from these projects, and my animations were built animations on top of that.

The simulation software is here: https://stevemould.com/bounce
