I need a big clear plastic ball, globe, bowl etc?

I want to make the torso of a snowman to wear as a sweater. So basically all I need to complete this is a clear ball (however it may be made) to hold fake snow. I think a 14in to 16in globe is a good enough size to work with for my body. I need answers ASAP!!! Haha. I'll be sure to give points. Please and thanks!!
