Ok here's it!
The buck ball is the third isotope of Carbon, the full name is buckminsterfullere, It consists of 60 C-atoms, therefore the formula is C60. C-atoms in this isotope are arranged in a form of a sphere that is made up of rings of 5 & 6 C-atoms, The sphere resembles the pattern of..umm a football! It's size is app. 1 nm
Other fullerenes have also been prepared, consisting varying no. of C-atoms like C70
Ok, Properties of Bucky Balls include :-
They are soluble in water, C60 gives a pink solution & C70 gives a red one.
They may be harder than diamond.
They are more slippery than Teflon (Yoi know what Teflon is, Don't you?)
They may be insulators or conductors.
I'll upload more later, because it's a lot Ok!

Ok for Carbon Nanotubes..
Discovery of Bucky Balls led to the discovery of Carbon Nanotubes
N-tubes are cylindrical in shape & resembles a rolled up sheet of graphite 6-C rings in the repeated form. They have a diameter of a few nanometres & can be open at either ends, or sealed at both.
Uses of N-tubes include
Due to stiffness, strength, toughness & Electrical properties of bucky tube materials, N-tubes are used in Batteries, Fuel cells, Fibres, Cables & In pharmaceutical & biomedical material.
Get it?
If you want anything else just post it here :)
Hope that helped!

You need to know complementary colours and their approx. wavelengths.
