![]() Come out and see us at Smith Voke, on April 30th, 2022. Hey! We’re doing a live show as part of The River's Family Music Meltdown and Book Bash in Northampton, MA. We’ll have free resources to learn more about how to make less trash - and new solutions for recycling - on the blog on our website at. ![]() To listen, pledge to support us on Patreon for just $1 a month or more, at /tumblepodcast. Learn how one city learned to make less trash, in a special bonus interview episode with Lily Pollans. Find out how science can help tackle Earth’s biggest challenges - and how you can help. Kevin Solomon hopes to solve the challenge of recycling plastic with the help of meal worms, and Lily Pollans is figuring out what kids can do to help everyone make less trash. In this Earth Day episode, we meet two researchers who are tackling trash in two very different ways. But scientists are coming up with solutions that might surprise you. Trash is one of the biggest problems on the planet. Wave the wand slowly or blow on it and enjoy the physics of giant soap bubbles! Dip a giant bubble wand with a fibrous string into the mixture until it is fully immersed and slowly pull the string out. Add the Dawn Professional Detergent and stir gently, to avoid causing the mixture to foam. The water should thicken slightly, like thin soup or unset gelatin. Let it sit for a bit so the guar hydrates. Combine the alcohol/guar slurry with the water and mix gently for 10 minutes. Mix the guar powder with the alcohol and stir until there are no clumps.

Hear from the inventor of edible bubbles, Li Wei Tan, in a bonus interview episode available on our ad-free Patreon feed! It’s available for just $1/month when you pledge to support Tumble at /tumblepodcast. Along the way, we’ll discover the answers to our listeners’ bubbling curiosity. Bubbles is here to save the day! We’ll find out how a normal, everyman physicist named Justin Burton became a superhero bubble scientist, on a quest to make a scientifically proven recipe for giant bubbles. These cases illustrate the usefulness of a guide extension catheter in endovascular therapy of complex infrapopliteal lesions.Why do bubbles pop, and why do bubbles have shadows? We’re in double bubble trouble with two listener questions. Thereafter, a balloon could be passed, and successful angioplasty was achieved. Using the guide extension catheter, we then safely delivered a 0.035-inch guidewire's tail to drill through the calcification. Although a guidewire could be advanced to the lesion, no device could be passed through the calcification. Another patient had a severely calcified stenotic anterior tibial artery lesion. We then deployed the guide extension catheter to maintain blood flow while ballooning for 15 min, resulting in good blood flow to the toes after device removal. In a patient with posterior tibial artery occlusion, early elastic recoil occurred after balloon dilatation. We successfully managed two cases of infrapopliteal arterial disease with the assistance of a guide extension catheter. These devices are commonly used for active back-up support. Guide extension catheters have been available since 2015 for peripheral endovascular intervention.
