Just look at these bananas turned into explosive radioactive potassium

Cody from Cody's Lab bought 10 kilograms of bananas at the store, then proceeded to extract 9 grams of potassium from them. He could have gotten about twice that, but his condensation device had a design issue that caused the condensate to solidify and clog the tube. Great fun to see him toss it in water at the end!
