Some inventions are useful, and some just leave you wondering how they even got made. This list covers 15 strange products that somehow found success, whether because of clever marketing, curiosity, or just pure luck. These odd ideas prove that sometimes, the weirder it is, the better it sells.

In 1975, Gary Dahl introduced the Pet Rock — a simple stone sold as a pet, complete with a carrying case and training manual. Despite its simplicity, it became a massive fad, selling over a million units in six months.

Combining childcare with cleaning, this onesie turns your crawling baby into a floor mop. While humorous, it raises eyebrows about child labor.

Designed for marathon runners, this device feeds tomatoes to the wearer during a run. Innovative or impractical? You decide.
7. Solar-Powered Flashlight

This flashlight charges using sunlight, which sounds like a smart idea. However, if the power goes out at night or during bad weather, you cannot charge it. It is not very helpful when you need it the most.
8. Rotating Spaghetti Fork

This fork runs on batteries and spins your spaghetti by itself. It might make eating a little easier, but it turns a simple thing into something more complicated.
9. Egg Slicer

This gadget slices eggs into even pieces, typically for use in salads or sandwiches. It’s handy, but you could achieve the same result with a regular knife. It just makes a simple job a little faster and neater.
10. Puff-N-Fluff Dog Dryer

A 12-year-old came up with this suit that helps dry your dog after a bath. It looked a little silly, but many people liked it because it actually worked. It kept your dog warm and your home less messy.
11. Pizza Cone Maker

This gadget lets you make pizza in the shape of an ice cream cone. It’s a fun idea that combines two favorite foods in a unique way. It is not really needed, but it adds a playful spin to regular pizza.
12. Shoe Umbrellas

These small umbrellas clip onto your shoes to keep them dry in the rain. They do help a little, but they look pretty strange. Most people notice the style more than the use.
13. Avocado Saver

This tool is made to keep your leftover avocado from turning brown. It sounds helpful, but many people say using plastic wrap or a container works just fine. It may not be worth the extra space in your kitchen.
14. Moustache Shield

This old gadget was used to keep moustaches clean while eating or drinking. It was popular in the 1800s when facial hair was a big trend. Today, it serves as a humorous reminder of how much grooming habits have evolved.
15. Fliz Bike

This bike has no pedals and holds the rider in a harness, so you have to run to make it move. It is a creative idea, but not very easy to use. Most people find regular bikes much more practical.
