How much smaller is a quark than an electron? How does the size of the Vatican City compare to Uluru? Is the Minecraft World bigger or smaller than Jupiter? Of course you’ve all wondered such things (and if you haven’t, just be a good sport and play along), and now you can see the answers for yourself with this fantastic ‘interactivity’ – The Scale of the Universe 2 by Cary Huang.

As you can see, seriously mind blowing and cool stuff! Thanks to Matthew, one of my Year 6 students, for sharing this one.
