Beware the Banana Rays — Waterproof Die-Cut Vinyl Sticker | 2.1" × 2.3"

Science is full of surprising facts. Some of them are just a little bananas.

The Beware the Banana Rays sticker is a waterproof die-cut vinyl sticker that brings together science, humor, and everyday curiosity. Part of the Arts & Crafts and Science Communication collections, this playful design takes inspiration from the internet-famous joke about bananas being “radioactive,” turning a fun scientific fact into a lighthearted reminder that learning can be entertaining.

The System

Some scientific facts sound completely unbelievable.

Bananas naturally contain small amounts of radioactive potassium, a perfectly ordinary part of their natural composition. The amount is far too small to pose a meaningful danger, but the fact itself has inspired plenty of science jokes, memes, and conversations.

Beware the Banana Rays embraces that playful side of science.

Science doesn't always have to feel complicated or intimidating. Sometimes curiosity starts with a clever joke, an unexpected fact, or a simple question:

“Did you know…?”

This sticker celebrates the idea that learning can be funny, approachable, and worth sharing.

Because curiosity is always worth pursuing—even when it starts with a banana.
