My favorite blog, Colossal, published a post a few days ago and I’m still geeking out about it. Japanese balloon artist Masatoshi Matsumoto created these unbelievably beautiful and intricate balloon sculptures — made without the benefit of any tools or additional materials whatsoever. No tape, glue, adhesive, nothing.

I mean…

Seriously?! Can you believe these?

HOW does he do this?? For more of his work, check out Matsumoto’s Tumblr and Facebook.
