You know Alexander Graham Bell invented the telephone. But did you also know that the Edinburgh-born innovator is the person we have to thank for the metal detector? He devised the contraption not as a way to look for loose change and other left-behind items on the beach, but in an attempt to help save the life of President James Garfield. (Spoiler alert: Garfield died anyway.)

In this week's all-new edition of The List Show, Mental Floss editor-in-chief Erin McCarthy is sharing the details of 35 key—but lesser-known—inventions devised by some of the world's greatest inventors.

Keep Your Cat Busy With a Board Game That Doubles as a Scratch Pad

No matter how much you love playing with your cat, waving a feather toy in front of its face can get monotonous after a while (for the both of you). To shake up playtime, the Cheerble three-in-one board game looks to provide your feline housemate with hours of hands-free entertainment.

Cheerble's board game, which is currently raising money on Kickstarter, is designed to keep even the most restless cats stimulated. The first component of the game is the electronic Cheerble ball, which rolls on its own when your cat touches it with their paw or nose—no remote control required. And on days when your cat is especially energetic, you can adjust the ball's settings to roll and bounce in a way that matches their stamina.

The Cheerble balls are meant to pair with the Cheerble game board, which consists of a box that has plenty of room for balls to roll around. The board is also covered on one side with a platform that has holes big enough for your cat to fit their paws through, so they can hunt the balls like a game of Whack-a-Mole. And if your cat ever loses interest in chasing the ball, the board also includes a built-in scratch pad and fluffy wand toy to slap around. A simplified version of the board game includes the scratch pad without the wand or hole maze, so you can tailor your purchase for your cat's interests.

Since launching its campaign on Kickstarter on April 23, Cheerble has raised over $128,000, already blowing past its initial goal of $6416. You can back the Kickstarter today to claim a Cheerble product, with $32 getting you a ball and $58 getting you the board game. You can make your pledge here, with shipping estimated for July 2020.

The Long, Fascinating History of Chocolate

Walk into just about any grocery or convenience store today and you're sure to find row upon row of chocolate in every imaginable form. While we have come to associate this sweet treat with companies like Hershey, chocolate has been a delicacy for centuries.

All chocolate comes from the cacao tree, which is native to the Americas, but is now grown around the world. Inside the tree’s fruits, or pods, you’ll find the cacao beans, which—once roasted and fermented—give chocolate its signature rich and complex flavor. While we don't know who first decided to turn cacao beans into chocolate, we certainly owe them an enormous debt of gratitude.

In this episode of Food History, we're digging into the history of chocolate—from its origins to the chocolate-fueled feud between J.S. Fry & Sons and Cadbury and much, much more. You can watch the full episode below.
