No-School Camps & Spewing Jack-O'-Lantern Experiment from Mad Science

Check out everything Mad Science has to offer!

By Mad Science of Palm Beach October 3, 2019

Wondering what to do with the kids on those no-school days? Mad Science of Palm Beach has the solution! Our No School Day Camps located at the Jupiter Lab offer fun, hands-on activities that will keep your children engaged, learning and sparking their love for Science. Each day has a different topic so the fun never stops.

All Camps run daily from 9:00 am to 3:00 pm at the Jupiter Lab, 401 Maplewood Drive, #2 in Jupiter, and are open to children in Kindergarten to 5th grade. 

The October and November dates include October 9, October 18 and November 11. They offer easy online registration by visiting https://palmbeachbroward.madscience.org/parents-register-c.aspx or calling (561) 747-3033. 

Future Chemistry Kids: October 9th Find out in this camp all about cool chemistry. We’ll explore the basics of chemistry with some radical reactions and slippery slime! Children will learn about molecules, chemical and physical reaction and so much more. 

Space Exploration: October 18th Grab your helmet and get ready to explore our solar system and beyond. Learn all about planets, moons, stars and space phenomena. We will even talk about some of the steps to live in space today and into the future!

Ooey Gooey Slime Day: November 11th From slime to putty, children will investigate sticky science with fellow junior scientists. They'll combine polymers, study matter, and test formulas to find the best sticky substance and have them compete in the polymer Olympics. Best of all... the slime and putty they make are theirs to keep!

Other Great Fun at Mad Science: 

Don’t forget they don’t only host camps in the Lab. Drop-in on Mondays from 10:00 am to 11:00 am for fun Homeschool STEM Labs. Each week is a different topic. 

Have a mini Pre-K Mad Scientist? Then the monthly Preschool STEM Lab the first Wednesday of the month from 9:30 am to 10:00 am might be the perfect fit. 

🎃 SPEWING JACK-O'-LANTERN REACTION EXPERIMENT 🎃

Check out the Spewing Jack-O’-Lantern Reaction experiment out on YouTube: 




WHAT YOU WILL NEED: 

  • Adult helper
  • A pumpkin (or a watermelon)
  • Tray
  • Marker
  • Cutting board
  • Knife
  • Spoon
  • Small cup
  • Aluminum foil 
  • Baking soda, 60mL (¼ cup)
  • Liquid dish detergent
  • Food coloring
  • Vinegar, 240mL (1 cup) 
  • Measuring cup

WHAT YOU DO:

Step 1: Have your adult helper cut off the top of your pumpkin. Use the spoon to remove all of the pulp and seeds.

Step 2: Draw a face on the pumpkin.

Step 3: Have your adult helper use the knife to cut out the face you drew. It is now a jack-o'-lantern!

Step 4: Place the jack-o’-lantern on a tray. Place a piece of aluminum foil in the center of the jack-o’-lantern to make a wall. This is to keep the foamy reaction near the jack-o’-lantern’s mouth.  

Step 5: Fill the cup with about 60mL (¼ cup) of baking soda, add 6-7 drops of food coloring, and 3 drops of liquid dish detergent. Mix the ingredients with the spoon.

Step 6: Place the cup inside the jack-o’-lantern, in front of the aluminum foil wall. The cup should be slightly tilted towards the mouth opening.

Step 7: Pour 120mL (½ cup) vinegar into the cup. What happens?

Step 8: Add more vinegar to the leftover baking soda to continue the reaction.

WHAT'S GOING ON?

A chemical reaction occurs between the baking soda, which is a base, and the vinegar, which is an acid. This acid-base reaction produces carbon dioxide gas, which is the same kind of gas that is found in the air we breathe out. The dish detergent traps the carbon dioxide gas in bubbles. Eventually, the gas pressure creates enough foamy bubbles to force the liquid out of the cup. Placing this reaction inside the hollowed-out watermelon creates a spooky effect as the foam oozes out!
