Steam Box Fail

Today I tried to do some steambending for materials experiment in my project. I made a steambox (With help of my dad), it looked beautiful and I made my own mold. But...dun dun dun...it didn't work out, unfortunatly the pot with the water wasn't air tight enough, which meant the steam escaped there before even going in the box. Despite this I will not be defeated!! I will push on and fix this!
