a. My favourite "How To" video would be the video on 'How To Escape From Handcuffs.'
b. It's my favourite video because it displayed an interesting way of escaping handcuffs and that I always wanted to figure out how to get handcuffs off without having to use a key. Its a good thing to know if you want to show your friends that you can get them off with having a key.
c. The most important tip in removing handcuffs is that you must remove the cover on the bobby pin for it to work effectively and also put the bobby pin into the keyhole and make a sort of hook so that you can unlock the handcuffs.
d. If I were to add another tip in removing handcuffs from myself I would get a normal bobby pin of normal size and is flexible so that you are able to make it unlock the handcuffs. If its not you won't have a good chance in removing the handcuffs.
