Sandboxels

What Sandboxels actually is

Well over five hundred elements are on offer here, from ordinary water and stone through to specific acids, gases, foods, alloys and living things. Reactions are modelled properly, so heating limestone drives off carbon dioxide and mixing the wrong two things makes a mess of the screen.

Why it is worth your time

The element list runs deep enough that you can accidentally do genuine chemistry, such as electrolysing water into hydrogen and oxygen and then igniting it.

Common questions

Is Sandboxels free?

Yes. Sandboxels is free and does not ask you to register or hand over an email address before you can use it.

How long does Sandboxels take?

Good within five seconds of loading. We file it under "Instant" — falling sand with hundreds of elements and real chemistry.

Does Sandboxels work on a phone?

Sandboxels really wants a mouse and a wide window. It will load on a phone, but the experience is built for desktop.

What kind of site is Sandboxels?

We list it under Sandboxes & Simulators — small worlds that keep running without you. The element list runs deep enough that you can accidentally do genuine chemistry, such as electrolysing water into hydrogen and oxygen and then igniting it.
