In fact, the moms behind the incredibly popular Kids Activities Blog (and the wildly successful companion Facebook page, Quirky Momma) have a new book out to jump-start your kids' summer vacation planning. Holly Homer, Rachel Miller and Jamie Harrington's The 101 Coolest Simple Science Experiments: Awesome Things To Do With Your Parents, Babysitters and Other Adults just hit bookshelves, and they gave SheKnows a sneak peek at one of their favorite projects ... dissolving ink T-shirts.

Check out an excerpt from the book: 

Science Question:

Why It Worked

The alcohol acts as a solvent and dissolves the ink as it saturates the shirt, causing the ink to spread.

Variations

  • If you don’t have an old shirt to spare, this same technique can be used on paper towels or coffee filters.
  • Try hydrogen peroxide or water and see how the colors change (or don’t!).

Tip: After your shirt is dry, wash it alone so the colors don’t bleed onto the rest of your laundry.
