You're trapped in a well with a goat and a slinky. Describe how you will escape.

I decided to change my random question and this is the one I got. However, after 20 minutes of thinking up and composing a plausible and practical escape method, blogger now tells me that I can only write 150 characters. Grrr. Here's the answer that I came up with. I shall have to go and ask blogger for a new random question.
 
I'm assuming that this is an empty well and a live goat.

First I will uncurl the slinky so that I have a length of wire. I will then tie the end of the slinky to one of my shoes and throw it up so that it hooks around the bar that I'm assuming is at the top of the well. I will then untie the shoe and make a harness out of one end of the slinky wire for the goat. I will break small portions of wire off the other end of the slinky and embed them in the soles of my shoes to create spikes to help me grip the wall of the well better. I will also make hand spikes for me to hold out of wire.

All my preparations now complete, I will hoist the goat (in its wire harness) up to the top of the well. I will then attach the slinky wire to myself and, using the goat as a ballast, begin to climb the walls of the well. The goat will gradually be lowered as I climb and will take some of my weight, making it easier for me to climb. It also means that, if I slip and fall, I will fall at a slower speed as the goat will go upwards as I go downwards and so I will reduce the chances of me injuring myself. When I reach the top of the well I will climb out, pull the goat up by the wire, set it free, then set out for civilisation.
