The rattlesnake envelope prank was first patented in the early 1900s. It gained popularity between the 1930s and 1950s, when joke shops and mail-order catalogs sold novelty items across the country.
It was sometimes marketed under names like:
- “Snake-in-the-Box”
- “Envelope Jack”
- “Jumping Snake”
Before digital entertainment, these simple mechanical gags were a go-to source of lighthearted amusement.

Is It Safe?
When made with lightweight wire and rubber bands, the prank is designed to surprise — not harm. However, responsible use matters.
Avoid using it:
- On people with heart conditions
- On individuals with severe anxiety
- On young children
- In official or serious-looking envelopes (bills, legal notices, etc.)
The best pranks are playful, not distressing.
