Interactive training in the World Health Organization’s hand washing steps.
Scrubbing each step provides more habit-forming fun than popping bubble wrap.
Check your progress in the game with virtual ultraviolet inspection. Germs show up as fluorescent spots.
Bubble Beats provides realistic training that translates into better hand washing at the sink.
Tracing a symbol for the thumb unlocks that scrub step.
The hands move to the correct position for scrubbing.
Trace along the scrub track to pop the bubbles and move the hands.
Each level has a different song. Choose from many musical genres from blues, big band, samba, ska, and many others.
Buy items in the store with the coins you earn from completing each level.
Place the items you purchased, to make the world your own.
As a reward for reading this far down the web page, we will share with you a hidden trick: tap 10 times in the lower left corner of the Choose Level page, and you will unlock all levels for the Bubble Beats handwashing trainer.
Most patterns are geometric shapes. But on higher levels, the upper- and lower-case letters of the Greek alphabet appear. Public health officials often use these letters to denote new strains of a virus or bacteria. The virus that causes COVID-19 went through several variants as the pandemic evolved, most famously the Delta and Omicron variants.
On Level 27, two Japanese characters appear: 志賀. These characters make up the surname of Kiyoshi Shiga (志賀 潔), the world-famous physician and bacteriologist, who discovered the bacteria responsible for dysentery. The organism was named Shigella dysenteriae to honor his discovery. Dysentery is easily spread through poor hand hygiene.
Bonus points in the game if you draw these characters in the correct stroke order!
To test whether the training works, we perform an external assay of handwashing proficiency. The scrubbing motions in the trainer are tightly tied to those same motions performed in real life.
