Low-cost inventions that accidentally made millions

A reader emailed me about his aspiration to become a millionaire. I asked: “Why me? I’m a person with an unexplained poverty.”

Joel (not his real name) insisted that my critical thinking skills could be valuable for his 30 business ideas inspired by his mother and that one dear friend who owes him lunch.

He was told that any of his ideas could make him a millionaire in two years. “Then, why don’t you ask them?” On top of his list is Project J which needs $16,000 to develop. It includes patent protection, manufacturing, marketing, plus the miscellaneous items like a celebration budget.

Armed with optimism, Joel presented his idea to private financiers and government funding agencies. They rejected him with the kind of speed usually reserved for swiping left on dating apps.

Back to zero. Still trying to avoid Lotto as his retirement plan, Joel was inspired by the successful Canva founder Melanie Perkins who democratized software designs for everyone.

Low-cost inventions

I told Joel to stop thinking like he’s building the next spaceship. You can’t beat Elon Musk on that. Instead, focus on projects that won’t burn your wallet. Start with small experiments. Train your brain to spot the extraordinary hiding in the ordinary — like inventors who made millions from ideas suspiciously looking jokes that got out of hand.

Take the cue from Devon Scott-Leslie who compiled a list of low-cost, wacky inventions that earned huge money. From that list, here are eight gems worth studying (and envying):

1. Lucky Break Wishbones by Ken Ahroni who sold plastic wishbones so everyone could make a wish. In 2004 alone, he earned more than a million dollars.

2. Yellow Smiley Faces – multiple inventors claimed ownership, possibly because they all wanted to claim the $50 million the design earned in its first year.

3. Slap Bracelet by Stuart Andrews who created one fashion accessory that gave parents and teachers mild heart attacks. Andres earned “six to eight million” in 1990 alone.

4. The Million-Dollar Homepage by Alex Tew who at 21 sold one million website pixels for a dollar each. It’s monetizing something small you need a magnifying glass to see it.

5. The Snuggie by Scott Boilen who combined a blanket and a poncho and sold it with delightfully ridiculous commercials. The result? Over $200 million.

6. Santa Mail by Byron Reese. Sold at $9.95 each for an“authentic” Christmas mail “from Santa” sealed and delivered to children. In 2002 alone, he earned $3 million worth of belief in Christmas magic.

7. The Pet Rock by Gary Dahl sold rocks in boxes with manuals. It required zero training that earned millions. Proof that sometimes the best business model is literally nothing.

8. Antenna Balls by Jason Wall. Those smiley balls atop car antennas brought in one million dollars in just a year. Who knew happiness could be attached to a metal rod?

These eight inventions succeeded not because their ideas were complicated, but because they were simple, funny, cheap and didn’t require an engineering degree — or a second mortgage.

Japanese ridiculous inventions

Americans aren’t alone in this. The Japanese mastered the fine craft of chindogu — the art of inventing useless gadgets to solve everyday problems no one actually complained about.

Ripley’s list of “16 Crazy Japanese Inventions” includes the butter grater, umbrella necktie, eye drop funnels.

The list goes like the silent karaoke microphone, sound catcher pillow, chopstick fan and the legendary banana case. But the crown jewel is the square watermelon.

Invented by designer Tomoyuki Ono, the square watermelon was intended to fit neatly in refrigerators and stop rolling around. Sold at $100 apiece, it became an ornamental luxury item. A US patent was secured in 1978, and the idea evolved into watermelons shaped like pyramids, hearts and other questionable geometries.

Does the world need square watermelons? Absolutely not. Did the world buy them anyway? Yes — and cheerfully because Japan is a gift-giving society.

The real lessons

Many people who boast of their “black belts” believe inventions should solve serious problems. That’s nice. But history shows that hundreds of inventions solve imaginary problems and still become wildly profitable.

Take the annual Harvard’s Ig Nobel Prize that honors “achievements that make people laugh, then think” like studying the slipperiness of banana peels.

The secret? Simplicity sells. Humor helps. Whether it’s a wearable blanket or a glorified stone pet, these creators broke the myth that inventions must be complex, expensive or earth-shattering.

If you can develop something without spending much money, that is the true definition of sophisticated innovation. Anyone can burn millions creating a product nobody wants. But inventing something cheap, simple and irresistible — that’s genius.

So, before you chase your next million-dollar concept requiring $16,000 in funding and a prayer, try asking: “What silly, low-cost idea can I turn into the next ridiculous success story?”

Some billionaires who work for the government may still out-earn you, but you’ll sleep better knowing you tried something simple, smart, honest and a little silly. Who knows? Your next million might just come from selling triangle-shaped mangoes.
