Discover the Magic of Rain with the Floating Rain Gauge

Harnessing the timeless brilliance of Archimedes’ water displacement principle, this rain gauge turns every shower into a show. As rain collects in the outer chamber, a sleek inner measurement tube gently floats upward, rising in perfect sync with the rainfall.
 No batteries, no fuss—just the pure elegance of physics in motion.

It’s not just a tool; it’s a conversation starter. Whether perched in your garden or displayed on a patio table, it offers a fun, eye-catching way to track precipitation. Practical, stylish, and undeniably cool—measuring rain has never been this satisfying!
 

A great example: My wife's garden is full of all kinds of flowers. It rained overnight, and the next day she wasn’t sure how much rain had fallen—or whether she needed to water the plants or not. With this device, created especially for this contest, she was able to tell perfectly if extra watering was necessary.

With its practical mounting bracket, the rain gauge can be easily attached anywhere using just two screws. 

And when it’s time to empty the water, simply lift the gauge out of the holder, pour it out, and place it right back—quick, clean, and hassle-free.

The package also includes a desktop stand, in case you’d rather not mount the gauge to a surface with screws. 

Additionally, it contains a version scaled in inches and milimeters.

Thanks to the clear scaling, you’ll always know exactly how much rain has fallen.
 

Printing guide:
 

Please select in the file whether you want to print the millimeter or the inch version, with or without AMS, and which holder you’d like to use. 
Do not modify the print settings for the inner cylinder — it must stay at 5% infill with Grid pattern (I know, I’m not a fan either, but it was designed this way to work precisely).

Enjoy every drop – happy rain measuring!
