Science you can poke at.
Fizzle is a set of small interactive experiments in chemistry, biology, and physics. Each one runs in your browser and does a single thing well. No accounts, no installs, no waiting. Pick one below and start poking.

What this site is
Every page here follows the same rule: one idea, one interaction, instant feedback. You do not read about periodic trends; you switch the color scale on the table and watch them appear. You do not memorize the parts of a cell; you click them and see what each one does. The demos are simplified on purpose, and each page says exactly where it cuts corners. When you want the numbers behind an experiment, the reference tables hold the constants and sources. When something surprises you, or breaks, the guestbook is the place to say so.
