Sure sure. Burn dried coffee grounds to repel mosquitoes. I can do that! Well no, actually I can’t. They make it look so easy in all those how-to videos floating around Facebook. I tried it. How in the hell do you get the grounds to burn and stay burning? I lit a paper fire underneath the foil tray. I lit paper twists stuck into the grounds in the tray. There was plenty of smoke, but it wasn’t the nice “just like burning incense” type that the videos showed. So, what’s the secret? Do I need one of those lobster-butter melters you get in restaurants?
Everyone who is seriously involved in the pursuit of science becomes convinced that some spirit is manifest in the laws of the universe, one that is vastly superior to that of man. – Albert Einstein
