After Dr Chia used his well-toned muscles to rip open the sweet, the torn sweet wrapper stuck to his finger for a few seconds before dropping due to gravity.

The friction between Dr Chia's fingers and the wrapper caused electrons to be transferred over. Thus, Dr Chia's fingers and the wrappers had unlike charges, which were attracted temporarily. After a while, since they were in contact, the electrons were transferred back, thus both Dr Chia's fingers and the wrapper had a net neutral charge, and the wrapper was no longer attracted to the fingers, and dropped to the floor.

When Dr Chia tore the wrapper, the wrapper was charged by friction, gaining a net charge, which caused it to be attracted to the particles on Dr Chia's hand, before being earthed and falling back to the ground.

When the sweet wrapper was torn into two, the friction between the two pieces of the wrapper caused one of the pieces to be charged by friction, leaving it with a nett charge. The wrapper was then attracted to the oppositely charged particles in Dr Chia's hand, causing it to stick to his hand momentarily, before being earthed by the hand and falling down to due gravity.

The friction between Dr Chias hand and the sweet wrapper caused the sweet wrapper to become charged, and thus attracting momentarily to the oppositely charged hand.

It was charged by friction when he tore the wrapper. Due to the net charge on the wrapper, his hand was polarised when the wrapper was brought close to it. As unlike poles attract, the negative/positive net charge on the wrapper was attracted by the opposite charges on the surface of his hand. This causes the wrapper to be stuck onto it. After a short period of time, the wrapper loses its net charge and is no longer attracted to the hand. Hence, it falls to the floor.

The wrapper and the hand are magnets so they attract each other

The wrapper pieces rub against each other and the friction between 2 different materials of the wrapper charges the wrapper. Because it has a charge, it will attract the person's hand.
