A fringe benefit of having a science teacher for an Aunt...nifty little projects like Sharpie tie dye! For one day--and one day only--I allowed them to color on their shirts with Sharpies!
Take one clean white t-shirt, scrunch it up and secure with rubber bands and color all over with a Sharpie...in and around all of the crevices. Soak the scrunches in rubbing alcohol...an old dosage syringe worked really well! Remove rubber bands, lay out flat to dry.
