The S.M.A.R.T. Squad girls, Izzy, Charlie, Allie, Gina, and Marie love to experiment. You probably do, too! So here are some D.I.Y. S.T.E.M. experiments you can try.
Marie’s “Do You Dare? Hair-dye Solution”
Want a winning streak in your hair? S.M.A.R.T. Squad’s chemist, Marie, has concocted the perfect solution. Use Kool Aid! Your new color won’t be permanent, and the dye will be easy to apply.
First, put on rubber gloves so that your fingers won’t be dyed and slip on an old tee shirt to protect your good clothes. It’s a good idea to have a small, clean paintbrush on hand to use, too.
1. Next, mix warm water, your favorite hair conditioner, and unsweetened Kool Aid in a disposable cup. Experiment with different colors (flavors) and amounts of Kool Aid until you’ve made the color of your choice.
2. Make a gooey paste.
3. Use the paintbrush to apply the paste all over your head if you want to dye all of your hair. Or paint the dye on in streaks to achieve the look that Marie is sporting.
4.Let dry, and let fly!
Here are two other ways to dye your hair temporarily, too:

Physicist Izzy’s fine with slime! Want to glom on?

Izzy’s “Ready for Slime Time” Recipe
First, cover your good clothes with an old tee shirt or an apron. Then follow these steps:
1. Put 1/2 cup of any old shampoo in a throwaway bowl. Add 1/4 cup of cornstarch. Mix well.
2. Add 3 drops of food coloring. (You don’t have to, but it’s more fun if you do!)
3. Add 1 tablespoon of water and stir. Slowly add 5 more tablespoons of water, stirring well after each one.
4. Knead the slime for around 5 minutes.
5. Have a fine time with your slime!

Math-loving Allie’s nickname is “Allie Oops,” because sometimes her projects just don’t add up. Once she mistakenly dyed all her clothes blue. But maybe you’re dying to try dyeing. So here’s . . .
Allie’s “Do-or-Die Tee Tie-Dye (This time, on purpose!)”
It’s best to do this outside, wearing one old tee shirt while you’re tie-dying another tee shirt that is clean, white, and cotton. Wear rubber gloves if you don’t want to dye your hands.
1. Put your tee shirt in a large plastic bowl. Pour ½ cup white vinegar
and ½ cup of warm water on the shirt and let the shirt soak for half an hour or so.
2. Wring the tee shirt so it’s just damp, not soaking wet. Roll it into the shape of a tube and slip three or four rubber bands around it, spaced out. Or, if you prefer, tie knots in the tee shirt.
3. Put ½ cup cold water in an old squeeze bottle and drop in about eight drops of food coloring. Screw the cap back onto the bottle securely, and shake it to mix the water and dye together thoroughly.
4. Squirt the food coloring and water mixture onto your tee shirt. Do all sides.
5. Mix up other food coloring colors with water and squirt those colors onto your tee shirt in different areas for each color.
6. Put your tee shirt in a plastic bag, seal it up, and let it sit overnight.
7. The next day, be sure you’re wearing that old tee shirt again. Take the wet tee shirt out of the plastic bag, take off the rubber bands, and plunge the tee shirt into a bowl that has ½ cup water and ½ cup salt in it to set the dye. Then wring the shirt out.
8. Dump out the salt water, fill the bowl with clean, cold water, and rinse your tee shirt over and over again until the water is clear. Wring out the tee shirt one last time and hang it up to dry.
9. Wear your tie-dye shirt and look cool. Remember: The first three or four times you wash your shirt, wash it separately in cold water or you will end up with unintended dyed clothes—just like Allie did!
Here are two other ways of tie-dying a tee shirt:
Naturalist Charlie eats all natural foods, naturally! Chomp on . . .
Charlie’s Chewy Chickpea Chow
1. Sprinkle as much feta cheese as you want over a big handful of raw spinach. Drain a can of chickpeas and toss them on the spinach, too.
2. In a separate small bowl, mix 3 teaspoons of honey with 4 tablespoons of olive oil, ½ tablespoon of lemon juice, and a small handful of raisins. Add a teaspoon of cumin, a pinch of salt, and ½ teaspoon chili flakes. Mix it all up really well.
3. Toss both parts of the salad together in a nice big bowl and chow down!

Gina, the S.M.A.R.T. Squad’s engineer, likes to aim high. If you like to send things flying, too, try building . . .
Genius Gina’s Gee-Whiz Catapult
1. Stack 9 popsicle sticks one on top of the other and use a rubber band to hold the stack together at one end.
2. Slide a 10th popsicle stick through the stack under the top four popsicle sticks and wrap another rubber band around the other end of the stick.
3. Attach a plastic spoon to one end of the vertical stick with a rubber band.
4. Put a mini-marshmallow in the spoon, tap the spoon, and send the mini-marshmallow soaring across the room!
