Jon Chase explains that angular momentum is what makes a spinning top, a bicycle wheel or an ice skater spin on an axis. He also shows how manipulating the different factors involved can conserve angular momentum, and make a spinning object more steady and spin for longer.

Here's how you can experiment with a bicycle wheel and dumbells to learn about angular momentum and gyroscopes: http://sirius.ucsc.edu/demoweb/cgi-bin/?mechan-rotate-rot_stool

Why is it easier to balance on a moving bike than a non-moving bike?

IMPORTANT: You will need one sober adult with a sense of scientific wonder to be present....

What you need to carry out this experiment is: Two 12 inch vinyl's, a biro, a cd marker, some string, a ruler, two CD's, 32 Two pence coins, some scissors, sticky tape, blue tack, a bolt with screw and a washer.
 
#1
1.     Make a mini spinning top by wedging some blue tack around about an inch up from the point of your pen.
2.     Now wedge your pen through the hole of a CD and put the blue tack firmly in place
3.     You can now spin and enjoy your homemade spinning top. 
 
#2
1.       Put your bolt through the centre of your vinyl.
2.       Now fasten the bolt and washer on the other side of the vinyl
3.       Now spin quickly and enjoy your giant gyroscope

#3
Experiment with mass by sticking 2 p's to your CD's and Vinyl's.
