Sandcastle science

Sandcastles are not only a cool thing for a child, but also are a good research topic...

Recently researchers discovered the secret to building the perfect sandcastle. You would never guess, but apparently, it's all in the water.

Now go make the calculations so that you can impress the rest at the beach this weekend.

PS: Don't you sometimes wonder who finances some researches?
