Celebrate the spooky season with a Science Halloween-themed science party or stage shows! Children of all ages will use science to figure out how to reverse a witch's spell on Count Eggbert. They will also experience creepy potions, a dry ice cemetery effect, ghostly bubbles and floating eyeballs that are sure to amaze everyone. Don’t forget about our awesome Halloween themed slime that includes ghostly goo, witches brew and pumpkin guts – which will you pick?
The best part about our Halloween parties is we bring the spooky, fun and mess and only leave behind the fun. We can perform both inside and outside and we have packages to accommodate any budget and party size. Call 561-747-3033 or visit https://palmbeachbroward.madscience.org/parents-birthdayparties.aspx to book your party.
SPEWING JACK-O'-LANTERN REACTION EXPERIMENT
(check out our Spewing Jack-O’-Lantern Reaction experiment out on YouTube: https://www.youtube.com/watch?v=4NrwpyNSi88
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 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!
