Christine Taylor-Butler - Bathroom Science: 70 Fun and Wacky Science Experiments

Put towels around the toilet to catch any potential spills, and put on the rubber gloves. In the plastic cup, mix the warm water with a few drops of liquid soap. Then add a few drops of red food coloring. Add the baking soda. Carefully place the cup into the empty toilet bowl. Pour the vinegar inside the cup.

Stand back! WHATS GOING ON HERE? The baking soda and vinegar erupt because of an acid-base reaction. Acetic acid (vinegar) reacts with sodium bicarbonate (baking soda). This creates carbon dioxide gas. The gas reacts with the remaining liquid to create the fizzing and bubbling effect. The liquid soap helps increase the amount of foam produced. WHAT YOU NEED 1 cup hot water 1 cup Epsom salt 1 cup school glue Glow-in-the-dark paint Paper bowl HOW TO DO IT Pour the water into the bowl and add the Epsom salt. WHAT YOU NEED 1 cup hot water 1 cup Epsom salt 1 cup school glue Glow-in-the-dark paint Paper bowl HOW TO DO IT Pour the water into the bowl and add the Epsom salt.

Rapidly stir until it starts to dissolve. Stir in the glue until smooth. Stir in about three tablespoons of glow-in-the-dark paint. Continue stirring until solid. Turn off the lights! WHATS GOING ON HERE? The glue (scientific name: polyvinyl acetate resin) is a polymer, which means many units. The combination of Epsom salt, glue, and water sets up a chemical reaction to form a compound that is solid.

The Epsom salt binds to the glue to make the glues polymer strands stronger, but still allows it to stretch. As for the glow, the paint contains phosphorous pigments that are activated when exposed to light.

GOOD SLIME IS SO HARD TO FIND THESE DAYS. YOU MIGHT AS WELL JUST MAKE YOUR OWN. WHAT YOU NEED 2 bowls 1/2 cup school glue 1-1/2 cups water Food coloring 1 teaspoon borax Resealable plastic sandwich bag HOW TO DO IT Pour the glue and half a cup of water into a bowl. Stir.

Add a few drops of food coloring. (Green is the most slimelike, but you can use any color you want. Or even more than one!) In a second bowl, add the borax to the rest of the water. Stir until the borax is completely dissolved. Slowly pour the colored glue mixture into the borax mixture, and stir the mixing concoctions as you do it. While there may be a little bit of extra water hanging around, the result should be a semisolid hunk of slimy green goop.

Pull it out of the bowl, and pull and squish your new slime! (To save the slime for future slime-requiring activities, store it in a resealable plastic sandwich bag.) WHATS GOING ON HERE? A compound is formed by combining two or more substances into a mixture that cant easily be separated. Glue + borax + water = compound. Additionally, glue is a polymer, which means it contains individual molecules that can slide past each other while still holding together as a substance. When borax bonds with water, electrically charged molecules called ions form. Those, in turn, more tightly link the polymer molecules in the glue.

WHY WOULD YOU WANT TO MAKE ARTIFICIAL SNOT? WHO NOSE WHY? WHAT YOU NEED 1/2 cup boiling water 3 teaspoons unflavored gelatin Medium bowl Green food coloring (If you dont have unflavored gelatin, you can use lime gelatin, and skip the food coloring.) 1/2 cup corn syrup Fork
