Myth (describe your myth)
-Marrying ketchup will cause a chemical reaction and cause the ketchup to explode. Marrying ketchup is when you dump one bottle of ketchup (may or may not be the same brand) into another bottle of ketchup. It's said that the gases will mix with with the oxygen and cause a huge explosion.

Vinegar- A sour tasting liquid containing acetic acid obtained by fermenting dilute alcoholic liquids, typically wine, cider,or beer used...
Acid- A chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red.
PH- A figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid.
Corn syrup- Is a sweetener made from cornstarch.
Chemical Reaction- Is a re-arrangement in atoms to form a new chemical.
Solid- Something that is firm or stable in shape, and it's not liquid or fluid.
Liquid- Something with consistent volume and flows freely, and has a consistency of water or oil.
Gas- An airlike fluid substance in which it expands freely to fill any available space irrespective to its quantity.

-Small Scale Procedure:
  • Question~ Does the ketchup produce gas on its on?
  • Independant Variable~ Amount of ketchup
  • Dependant Variable~ How big the balloon gets.
  • Constant variable~ The brands of ketchup used.
  • Hypothesis~ If we put a brand of ketchup in a flask then will it cause an explosion ON ITS OWN because the gasses of its self mixed and caused a chemical reaction.
  • Materials~ 2 brands of ketchup
1 graduated cylinder
2 flasks
2 balloons
your journal
a pencil
  • Procedure~
1) Open the bottles of ketchup
2) Gently 'dump' one brand into the graduated cylinder
3) Measure out 10mL
4) After you have 10mL of ketchup in the flask, pour the ketchup from the flask and into one of the flask.
5) Put a balloon over the top of the flask
6) Repeat steps 2-5 for the OTHER brand of ketchup
7) Observe ow big the balloon gets over the next course of the week
-Small Scale Conclusion~
  • Nothing really happened in either flask. The only interesting thing, was when the ketchup separated from the oils. You could barely notice the balloons as they got bigger. And that's because they really didn't get any bigger. Maybe a few centimeters, but not enough to make an actual explosion. As for the different brand, the one ketchup which DID have High Fructose Corn Syrup, seemed to have a bigger mass in its balloon. I'm assuming, HFCS affects how big the balloon gets.. But I'm not so sure as if right now.

-Large scale procedure:
  • Question~ Will mixing the ketchup cause an explosion?
  • Independant variable~ Amount of ketchup in the flask.
  • Dependant variable~ The balloon (how big it gets(
  • Constant variable~ The brands of ketchup used.
  • Hypothesis~ If we mix the ketchup together, then will it cause it to explode, because of the gases mixing together and creating a chemical reaction?
  • Materials~ 2 ketchup bottles (may or may not be the same brand)
1 graduated cylinder
2 flasks
2 balloons
your journal
a pencil
  • Procedure~
1) Open the bottles of ketchup
2) Get the graduated cylinder
3) Pour ketchup into the graduated cylinder
4) measure out to be 20mL FIRST TIME, 2nd TIME 30mL
5) Gently, pour the ketchup that's in the graduated cylinder into the flask
6) Be careful not to spill or leave any ketchup residue in the graduated cylinder
7) Put a balloon over the opening on the flask
8) Repeat steps 2-7 for the 2nd flask/test
9) Over the course of the next few days observe what is happening with the balloons
10) After 2 days, take off the balloons from each one
11) pour the ketchup that's in the flask into one flask. (so dump one flask contents into the other)
12) Put the balloon back on
12) Observe for a few more days, making observations with your journal and pencil
-Large Scale Conclusion:
  • This is not possible at all. From all the data I collected, it shows that some gas was produced, but not enough to cause a chemical reaction. Even when I mixed the ketchup, i saw a little more gas being produced but it was still to little. The ketchup still acted the same way it did in the small scale test. It still separated from the ketchup, the oils did that is.
-This myth is BUSTED! It's not possible that marrying ketchup will cause an explosion. There's always been too little gas to do anything that big such as a big explosion as the myth describes.
