Glad to see you're enjoying the cutting-edge science available onsite. I hope your daughter is equally as happy to know her experience is something many of us can recreate, although perhaps not all it sounds like!

I do enjoy beetroot, don't get me wrong, but all day - and in bizaare variants such as orange soup, salad, pie etc. - it just gets too much by half. Ugh. Still, it is some time since I myself was a student, and back then cheap cold baked beans and 5p noodles were more than enough for me. I guess beetroot - an actual VEGETABLE of sorts - would have seemed like intense luxury!

So far, you've convinced me that yourself, and hence many, maths teachers might be human. I can't imagine robots, or aliens, taking an interest in strangely-coloured bodily fluids. Only our species has the intellectual capacity to conceive of such wonders, I'm sure you'll agree.
