WTF is going on and why would you do that to yourselves?
Not only is this dangerous (some people have had the glass shatter or the blood vessels in the lips explode) but it looks so stupid and nothing like Kylie Jenner's lips, even hers are not that big.
If you really want lips like Kylie Jenner doing this challenge isn't going to get you get them, she very clearly as lip fillers which she then further accentuates with the use of lip liner and lipstick.
I do not agree with a 17 year old having fillers injected in her lips and no person of that age should want or need to do so so I'm going to show you how to achieve a similar pouty look with just the use of makeup.

Step 1: Cover your entire lip area with concealer
Step 2: Use a light flesh toned lip liner to line just outside of your natural lip line and fill the whole lip area in with the same shade.
Step 3: Use a darker, more brown toned lip liner to shade the very outer edges of your mouth.
Step 4: Fill in with a brown matte lipstick.
Ta da your done and not a needle or cup in sight!
