Rational?!

There are a number of these near the gym, the colours are lovely and so is the smell. But for some strange reason I keep thinking that they are like something out of the Adventure Game (1980's futuristic game show for younger blippers) or Dr Who. I expect that at some point they will move and if I look round quick enough I'll catch them!! Very irrational!!

Now where did I leave those marbles......
