but it's certainly going to be a hit with scientists,

because researchers have watched how the tiny platelets that help our blood to clot get formed in the first place.

So that's all on the way.

And also this week we'll be looking at the science of robots and how scientists are now creating clever machines that can carry out crowd control,

Plus in this week's question of the week we're getting to the bottom
