This is a video of inevitable medical bill GoFundMe recipient Backyard Scientist and his friends pumping a watermelon full of 20,000 volts in a split second. They also try to cook a steak using the same method, which just gets a hole blown right through the middle. Electricity: it's terrifying. I especially liked the part where they didn't realize the capacitor still had a charge in it and they all surprised themselves with a huge spark. Death: he's knocking at your door. I also liked the part where a neighbor threatens to call the cops and The Backyard Scientist's dad yells at them. I didn't like the part where I wasn't invited.
Keep going for the video, but skip to 2:45 if you don't have time for science and just want to see things blow up.
Thanks to Dougie, who agrees this kid has put his neighbors through enough.
