Childhood toys haven’t always come with the safety standards parents expect today. For much of the 20th century, children played with products involving sharp metal, extreme heat, powerful projectiles, and even chemicals that would raise immediate concerns now.
Some were eventually recalled or redesigned, while others simply disappeared as safety regulations became stricter. These 16 toys show just how different the definition of acceptable childhood fun once was.
1. Jarts Lawn Darts

These weren’t lightweight plastic darts. Original Jarts featured heavy metal tips designed to fly through the air and stick into the ground. After serious injuries and deaths involving children, lawn darts with pointed tips were banned for sale in the United States.
2. Gilbert U-238 Atomic Energy Lab

Released in 1950, this elaborate science kit included actual uranium ore samples alongside instruments for experimenting with radioactivity. It remains one of the most astonishing children’s products ever commercially sold.
3. Creepy Crawlers Thingmaker

Children poured liquid plastic into metal molds and heated them on an electric hot plate to create rubbery insects. The original version could reach temperatures capable of causing serious burns.
4. Johnny Seven OMA

One of the hottest toys of 1964 was essentially seven toy weapons combined into one enormous plastic gun. It could fire several types of projectiles and looked remarkably realistic by modern standards.
5. Clackers

Two hard acrylic balls attached by a cord were swung rapidly until they smashed together above and below the user’s hand. Some versions could shatter on impact, sending pieces flying.

6. Vac-U-Form

Mattel’s Vac-U-Form let children heat sheets of plastic over an exposed heating element before molding them into different shapes. It was creative, but it also put very hot equipment directly into children’s hands.
7. Sky Dancers

These fairy dolls launched into the air when children pulled a cord. Their unpredictable spinning flights resulted in reports of eye injuries, broken teeth, and facial cuts, eventually leading to a massive recall.
8. Battlestar Galactica Missile-Firing Toys

Mattel produced Battlestar Galactica vehicles with small spring-loaded missiles. After a child reportedly died from choking on one of the projectiles, the toys became part of a major safety controversy.

9. Slip ‘N Slide

The backyard favorite was designed for children, but adults and teenagers who used it faced a much greater risk because their additional weight could cause sudden stops and serious spinal injuries.
10. CSI Fingerprint Examination Kit

A 2000s toy doesn’t seem particularly vintage, but this CSI-branded forensic kit became notorious after testing reportedly found asbestos in fingerprint powder included with certain kits.
11. Austin Magic Pistol

Transogram’s Swing Wing was worn on the head while children rotated their necks to make a long plastic streamer spin around them. Watching the original advertisements is enough to understand why the concept didn’t endure.

13. Super Elastic Bubble Plastic

Children squeezed chemical goo from a tube onto a straw and blew it into colorful plastic bubbles. The product’s strong solvent fumes and direct mouth contact would make it a difficult sell to parents today.
14. Metal Playground Merry-Go-Rounds

These spinning playground fixtures weren’t technically take-home toys, but they were a defining part of childhood play. Kids pushed them as fast as possible before jumping aboard, often with little preventing someone from flying off onto a hard surface.
15. Wood Burning Kits

Children could use electrically heated metal tips to burn drawings into pieces of wood. The creative possibilities were endless, but so was the opportunity to touch an extremely hot tip accidentally.
16. Toy Metal Casting Sets

Some vintage casting kits allowed children to melt metal and pour it into molds to make toy soldiers and other figures. It was essentially a miniature foundry marketed as a children’s hobby.
