Once our casts were fully dried we added the expanding foam. It came in a two part mixture which is mixed in a 2:1 ratio. it has to be stirred very quickly with a decent amount of force as it start going off almost instantly. Once you'd stirred it for around 10 seconds it was poured into the foot holes of the cast and swirled around. First time I did this I hadn't mixed it vigorously enough meaning the texture of the foam was not quite right, I also didn't use quite enough hence there being no legs below.
I enjoyed the workshop and definitely learned a lot about sculpting/model making however it is not a branch of animation I'm particularly interesting in I'm glad I got the opportunity to experiment with it but it's not something I'm itching to continue
