Entry #3, has an amazing erlenmeyer flask. The liquid is cool too, but the glasses end up making the design look like it has silly googly eyes. Though fun, it lowers the demographic to look like we're focused towards kids.
Entry #4, awesome. Great colors and design. Would like to see variations.
We like #16 quite a bit, but we're not so fond of the bubble design (the reflections just seem a bit off, they almost look like tiny olives with pimentos), but we like the "carbonated drink" effect, is there anything you can do to improve it in that direction?.
Also it's a bit nitpicky, but the curve radius of the bendy straw seems a little out of proportion with real life.
