Materials At least two rubber bands At least two plastic cups Colorful assortment of permanent markers Water 70 percent isopropyl alcohol aka rubbing alcohol Medicine dropper White T-shirt that can be dyed Newspapers optional This is to protect your work surface.
Hair dryer optional Preparation If you want to protect the surface on which you will be dyeing your T-shirt, cover it with a few layers of newspaper sheets. Note that permanent markers can stain fabric and other materials, so be careful when using them.
Procedure Lay out the T-shirt on the surface where you will be dyeing it. Wherever you want to make a design on the T-shirt, place a plastic cup underneath the shirt which should be flat so that both layers of the shirt are stretched over the cup and then loop a rubber band around the edge of the cup, going from the front of the T-shirt. This should end up making a flat, tight circle of the shirt fabric stretched over the cup opening. Do this to at least two places on the T-shirt so that you have at least two flat circles in which to draw.
Use the permanent markers to draw some colorful designs in each flat T-shirt circle that you made with the cups. Fill in at least two flat circles with your drawings.
Use the medicine dropper to drop a few drops of water onto the center of one of the flat circles that you drew in. Permanent markers, like Sharpies, are hydrophobic.
Try dropping a few drops of food coloring in water and oil to watch if and how it dissolves. For even more fun, check out our mega pack of insanely cool science experiments for kids. This was a delightful activity for my 6 year old and I!
Thanks again. How fun, Stefanie! A lot of these will help with my 11 yr old, Thank You. Your email address will not be published. Submit Comment. Sharpie Tie-Dye Science. Choose another color and make more dots. The circle of color should be about the size of a quarter. Now slowly squeeze about 20 drops of rubbing alcohol into the center of the circle of dots. Drip the rubbing alcohol really slowly. What do you see happening to the ink? Let the ink dry for about 5 minutes and then you can move the cup to a different part of the shirt.
When you are done making colorful circles put the shirt in the dryer for about 15 mintues to set the colors. The permanent ink of Sharpie pens is hydrophobic. It will not dissolve in water.
