They Looked So Cool in the Comic Book Ads: 14 Toys That Let Us Down Hard

1. X‑Ray Specs – “Cardboard Illusion Glasses”

We all wanted to be spies or superheroes, flash those specs and boom, see through walls! Instead, what arrived was a pair of cardboard lenses sandwiching a feather. The “lenses” consist of two layers of thin cardboard with a small hole about a quarter-inch (6 millimeters) in diameter punched through both layers. The user views objects through the holes. According to sources, in the original version, a feather is embedded between the layers of each lens. The vanes of the feathers are so close together that light is diffracted, causing the user to receive two slightly offset images. As one Redditor recalled, the effect was minor: “Each ‘lens’…holding a red feather. Looking through the feather made the subject look ‘thinner’ rather than a true x-ray.”  They didn’t reveal bones or secret files, just shabby illusions that fizzled fast.

2. Sea‑Monkeys – “Brine Shrimp in a Bowl”

Comic ads sold an underwater family with tiny crowns and castles. Im reality? It was a few ant‑sized brine shrimp in lukewarm water. One user summed it up as: “Sea monkey disappointment… Should be called ‘water lice.’”  Another remembered the fantasy box with a broken heart and commented; “My jaw dropped… then I beheld three small packets and a drinking glass.”  Although they hatched sometimes, they rarely lived long, or looked anything like their magical illustration.

3. Joy Buzzers – “Sad Shock Toys”

The “joke buzzer” or “joy buzzer” is a classic prank toy that became popular in the 1970s. It’s a device that looks like a button or a switch, and when someone presses it, it emits a loud, surprising buzzing sound. While not an actual electric shock, the buzzing is loud enough to startle the unsuspecting victim. These were tagged as laugh-out-loud prank zaps, perfect for petty revenge. But the truth is, all you’ve got are plastic buzzers that worked for a while until they didn’t. There’s no thrill, just instant disappointment when the shock fades after a handful of uses, leaving just a limp buzz and a deflated grin.

4. Switchblade Comb – “Spy-Gadget Comb”

It looked like a secret agent tool, that you could flip open and what you expected would be a comb blade. Unfortunately, mail-order versions often came with broken springs or flimsy plastic teeth. As one collector observed, store-bought combs fared far better. These failed gadgets couldn’t even hold a comb together. Did they call it a spy fantasy? Nah, it’s more like flat failure.

5. Cardboard Submarine – “Pool‑Safe Submarine”

We all dreamed of commanding a vessel beneath the waves, and comic ads promised a “7‑foot long” submarine you could sail. But in reality, it was a corrugated cardboard hull that couldn’t go near water. One Redditor put it bluntly:  “It wasn’t going in our pool. I was so disappointed when I learned that ‘200 lb. test material’ was corrugated cardboard.” Another nostalgic recount remembers assembling that paper contraption only to toss it in the trash. The end product was not quite the submarine adventure everyone pictured in anticipation.

6. Spy Decoder Ring – “Decode Regret Ring”

These felt so official, it was advertised that you could join secret clubs, send covert messages, and unveil hidden truths. But in truth, most decoder rings were cheap pins or didn’t even decode anything meaningful. As one blog recounts in reference to A Christmas Story: “Ralphie felt ripped off because the first message he decoded was simply an advertisement for Ovaltine.”  However, kids got excited, and trade‑marked commercial slogans instead of secret intel. 

7. Charles Atlas Course – “Pamphlet Muscle Plan”

The Charles Atlas course, popular in the 1970s and beyond, focused on building a stronger, more muscular physique using bodyweight exercises and dynamic tension. It emphasized building strength and endurance through specific routines and a balanced nutritional approach, aiming to transform individuals into more confident, physically developed men. What arrived? A pamphlet of push‑up and sit‑up routines, eating tips, and motivational blurbs. Although some adults swear it worked if you actually did the exercises, but for impatient kids, it was a letdown because there was no instant muscle, and no flexing poses, just paper and effort.  

8. Ventriloquist Dummy – “Fake Puppet, No Performances”

The comic ads promised a buddy puppet you’d master voice tricks with, along with stand-up shows in the living room. But what showed up? A thin, brittle “dummy” that barely opened its mouth and looked more like a mold reject than a stage star. One Redditor confessed: “I asked for a Danny O’Day ventriloquist dummy and got one for Christmas and ended up being a small, thin, flimsy disk”  So much for performing “Otto” or “Farfel”; no laughs, no magic, just quiet disappointment.

9. Sneezing Powder & Onion Gum – “Tiny Prank Fails”

The infamous April Fools’ Day prank products, like “Sneezing Powders” and “Stinky Onion Gum,” promised hours of joke-filled fun but often fell flat. Kids would eagerly await the powerful sneezes and onion-spiked breath, only to be left with faint powders or stale gum that failed to deliver the expected effect. Many recall the disappointment of sniffing powder that didn’t induce sneezes or chewing gum that barely tasted like an onion. The real prank, it seems, was the letdown itself, leaving users feeling disappointed and, well, pranked. These novelty items remain a nostalgic reminder of the humor and disappointment of childhood pranks

10. Fake Ice Cubes with Flies – “Gross Plastic Blobs”

This toy looked hilarious, it was advertised to have had clear cubes with little plastic flies inside, and sometimes it could come as cool “magic rocks” that crystallized in water. What we got was plain plastic blobs that felt gooey, looked tacky, something that made mothers cringe. Reviews for modern versions confirm what we suspected, some reviews said: “paint may wear off easily and the product starts looking fake and plastic”  

11. Magic Rocks – “Crystal Curiosity, Then Boredom”

These kits promised colorful crystal blooms overnight. For a while, that was actually true and it came as a neat, mini geology in action. But once that slow bloom stopped, we stared at dusty crystals growing inside a cup. Was it fun? Yes, but briefly. Was it long-lasting? Unfortunately, nope. We were left staring and wishing we’d planted a tree instead.

12. Tiny Monkeys – “Mail‑Order Monkey Mishaps”

13. Invisible Ink Pen – “One‑Message Wonder”

The promise was that this pen could write secret letters that vanish unless revealed. But the reality is that, by the second note, the ink was gone. One comic-series cartoon even advertised a decoder ring alongside invisible ink, still, there was no upgrade and most pens ran dry after just one or two messages. Due to this, its once peaked delight faded quickly.

Those comic book ads made it sound like keeping a cheeky, planet-sized pet on your shoulder was totally normal. But in reality, kids got a tiny squirrel monkey in a shoebox-sized crate, often half-starved, terrified, or unwanted. One buyer in the early 1970s recalled getting a primate in a “little cardboard box” with just a screen window and then ending up in the ER after being bitten badly. Parents soon discovered that these exotic animals need space, care, and serious vet bills, which does not associate with pocket pets. It was more about crisis than cuteness. 

14. Egg‑Hatching Kits – “Incubator Disappointments”

The ads promised magical chicks hatching in your bedroom. What did they create instead? A shaky incubator kit that rarely succeeded, often because the eggs died in transit or the unit didn’t work right. Many modern incubators barely hit 50% hatch rates, and sporadically shipped eggs might yield 20% or none. Reddit anecdotes show that many kids never saw a chick. Even experts say incubation is practical only with well-sourced fertile eggs and quality units. What arrived was frustration, not fuzzy newborns, and everyone learned a lesson that baby farm animals don’t grow on comic pages.
