Burping bags, yep kids love this easy science! Our bursting bags outdoors science activity is a MUST try and a classic. Experiment with a baking soda and vinegar reaction that’s a real blast. Kids love things that fix, pop, bang, explode, and erupt. These bursting bags do just that! We have tons of simple science experiments and STEM activities you are going to love to try!
BURSTING BAGS OUTDOOR SCIENCE
This simple science activity has been on our to-do list for awhile now because it’s a classic! Sometimes referred to as the exploding lunch bag, our bursting bag outdoor science is the perfect way to get your kiddos excited about science! Who doesn’t love something that explodes.
Baking soda and vinegar reactions make for exciting science activities.
Baking soda and vinegar chemical reactions are fascinating, engaging and easy for everyone to enjoy! Our latest bursting bags experiment is perfect for an outdoor science activity.
Actually it’s best to take this one outdoors because it could get quite messy. Perfect for a nice day to get outdoors for summer science.
BURSTING BAGS OUTDOOR SCIENCE INFORMATION
Even the youngest scientist can learn a little something about the science behind the bursting bags. The chemical reaction between the baking soda and the vinegar creates a gas called carbon dioxide. You can see this in fizzy drinks like our fizzy lemonade science activity!
The gas then fills the bag. If there is more gas than room in the bag, the bag will burst, pop, or explode. Similar to a volcano science activity erupting. There’s no place for the gas and liquid to go but up and/or out.
The key to really cool outdoor bursting bags is getting the right ratio of baking soda and vinegar. This is also what makes it such a fun science experiment for kids of multiple ages. Older kids can record data, make careful measurements, and re-test. Younger kids will enjoy the playful aspect of it all.
BURSTING BAGS SUPPLIES
Head to the kitchen to gather your supplies. A well stocked pantry especially with plenty of baking soda and vinegar ensures that you have fun science on hand any time you want!
Put together a homemade science kit to kick off your science adventures. The dollar store also has some great additions. Grab a box of gallon bags while you are there!
Gallon Size Bags (we did not use the zip lock ones)
Tablespoon Measure and 2/3 Cup Measure
Safety Goggle or Sun Glasses (always be safe)!

HOW TO MAKE BURSTING BAGS
We chose to use the toilet paper method to slow down the chemical reaction enough that we could see what was happening with our bursting bags! It’s all about the anticipation.
We had to change around the original recipe from Steve Spangler as it wasn’t working for us. We also seemed to have had strong bags (which were store brand). Dollar store bags may produce different results.
As you can see there’s lots of room for experimentation here! Next time, we might just try out the small sand which size baggies instead.
To get started with your bursting bags outdoor science project, you want to create a toilet paper pouch for the baking soda.
- Take one square of toilet paper and place a heaping tablespoon of baking soda in the middle.
- Bring corners together and wind up top to create a simple pouch.
- Add 2/3 cup of vinegar to gallon size bag.
- Seal the bag so there is just enough room to slip in pouch.
- Give a little shake and toss on the ground.
- Watch and see what happens with your bursting bags.
- Will they pop, burp, explode?
We attempted to follow the instructions from Steve Spangler, but we were not having any luck. We decided to experiment with our bursting bags on our own. What did we need to change?
Experimenting is what kid’s science activities is all about.
I am glad we did not have immediate success with our bursting bags science activity.
The problems our bursting bags had presented my son with opportunities to think of solutions. He needed to use his critical thinking skills to brainstorm new ideas.
I love that he wanted to keep trying more of these almost bursting bags. He was excited to see if the next bursting bag would work better or differently.
With a little assistance from a pool noodle below, he was able to make one of the bursting bags burst!
We did finally have success with our bursting bags. The one below grew and grew until it popped the bottom seam! I wonder what would happen if we added food coloring to the activity?
How will you try this bursting bags outdoor science activity?
Some of the bursting bags exploded in the middle of the bag while a few others just let out a little burp. Simple variations in each set up caused different reactions.
BURSTING BAGS OUTDOOR SCIENCE IS A BLAST!
