In this episode of Tiny Show and Tell Us, we explore a listener’s tip about a new source of tire rubber — the Russian dandelion — and the science behind what makes it such an incredible and sustainable source of natural latex rubber. Then we answer a listener’s question about a vaccine for fentanyl that will stop the drug from reaching the brain, preventing overdose.
