Tuesday may seem like just another day in the week, but on Instagram, Tuesday is the day to post evidence of transformation by posting before and after photos.

Every Tuesday teenagers post photo collages of themselves as a baby, when they were short, heavier, thinner, had a different style, next to a recent photo.

Without fear teens show how they change throughout the years. It takes time to edit the photo, hashtag it #TT, and upload it. And of course teens enjoy seeing the number of likes they get.

Tuesday, on social media, is a fun day for teens who want to show their transformation.

Sometimes this is good and Instagram is the best place to do it. Edit a photo, hashtag it #TT, and upload it!
