00:12 Mould effect
It's obvious that the weight of the heavy falling beads is pulling the remaining beads from the pot. However, it's not so obvious what's causing the large arc and why the beads don't just slide directly over the edge of the pot. It's said that you should view the chain as a series of short ridged rods rather than a flexible string of isolated beads.

00:47 Cool pressure trick
Heating air causes it to expand and cooling it causes it to contract. The boiling water in the bottle causes the glass to get very hot so the air inside the glass also gets hot causing it to expand. When the bottle is put into the cold water it quickly cools causing the air inside to contract rapidly which creates a vacuum and sucks the water up.

01:54 The lenz effect
"Lenz's law states that the current induced in a circuit due to a change or a motion in a magnetic field is so directed as to oppose the change in flux and to exert a mechanical force opposing the motion." When the magnet is dropped into the conductive alloy pipe it causes a change in magnetic flux. This change in magnetic flux creates a current in the Aluminium pipe which opposes the change and slows the magnet down in order to reduce the change in flux.

02:56 Anti-gravity water trick
There are a couple of forces at work here, air pressure and surface tension. The atmospheric pressure all around us helps to hold the plastic in place. In addition to this, there is a small pocket of air at the top of the bottle. Because no more air can get to this pocket an area of low pressure is formed. A combination of low air pressure inside the glass and higher air pressure outside of it help to keep the plastic in place.
Next is surface tension and adhesion. Water molecules are attracted to each-other like little tiny magnets with a positive and negative end. On the surface of the water, the molecules are able to get closer to each other than below the surface, this creates a sort of elastic surface layer.

04:16 Water on a string surface tension trick
^^^This trick works on the same surface tension and adhesion principles as the one above ^^^

04:52 Ring catch chain trick
The trick with this one is in how you drop the ring. If you let go of the ring with both fingers at the same time it would just drop to the floor. What you need to do is just release your thumb and keep your finger still. When you do this it causes the ring to fall at an angle which in turn causes the chain to loop itself over the ring and get caught.

05:43 Fork and spoon center of gravity trick
Every object has a center of gravity. This is the central point at which gravity acts upon the object. When you position a fork, spoon and toothpick in this way, the center of gravity or the pivot point happens to be completely central and towards the far end of the toothpick which just looks so wrong. It looks even more impressive when you burn the toothpick at both ends, this has no effect on the centre of gravity so everything remains balanced. The reason the toothpick does not continue to burn past the metal of the fork or the glass is that when it reaches these points it's robbed of its heat and goes out.

I came here to make sure Steve got credit and his effect was named correctly. Proud of you.

A similar demonstration of the dropping magnet is a solid metal disk connected to a pivot so it swings through the jaws of a large powerful magnet. The metal disk is not attracted to the magnet, but when allowed to swing through the magnetic field its motion is slowed and almost stopped. If a series of closely spaced slots are cut into the disk and the experiment repeated, the disk swings through almost unhindered. The slots disrupt the currents needed to generate the opposing magnetic field.

Very cool stuff. At first I thought, "They need to explain these effects verbally." Then I saw the written notes. You have pointed out some very good examples of how Physics can be weird, and provided links and explanations for effects. Very Good job!
