Lava lamp simulator FAQ

How does the lava lamp simulator work?

Each blob of wax has its own temperature. Near the hot bottom it warms up and becomes lighter than the liquid, so it rises; as it travels it cools, gets heavier and sinks back into the pool. Blobs that touch melt into one, and big rising blobs can split in two.

Is this lava lamp simulator free?

Yes. It is free with no sign-up and no watermark, and it runs in your browser.

Can I play with the wax?

Yes. Tap a blob to warm it up and send it rising, drag through the liquid to stir, or tilt your phone to lean the flow.

Can I record my lava lamp?

Yes. Save a PNG picture, or a 10 to 60 second MP4 or WebM video that loops seamlessly, in vertical, square or wide format.
