And don't clean your model first using rubbing alcohol. I learned that lesson the hard way and my glass water globe was stuck to the silicone. After that I don't think I would use anything except water to clean off a model. I also have used Lego bricks to make a mold box and it worked really well. :D - Heidi

I love your videos Paul but, Please, Please, Please get rid of that annoying music it's very distracting and I hate all videos where the music drowns everything being said out!! Thank you.
