I'm doing this experiment to see how acidic soda is to you because if I use marshmallows it will show if it dissolves quick it won’t take a lot of time to do the same to your stomach  

Manipulated / Independent Variable

ONE thing that you will test/change: 

Which soda i put in the jar

Coca Cola

Crush

Mountain Dew

Responding /Dependent Variable

The thing I think will change or be affected:  The Marshmallow

How will you measure it? : 

How fast will it dissolve in soda

Controlled Variables

Things we have to be very careful to keep the same every time we test so that they do not affect the results/outcome of the experiment: 

Jars ,Stopwatch, tape, amount of soda, size of marshmallow

• Coca cola
• Crush
• Mountain Dew
• Jars
• Marshmallow’
• Tape 
• Timer
• Tape marshmallows to a jar
• Fill jars with soda (1 cup) and start timer
• Turn off timer when it dissolves

My theory is that the gelatin was the component that stopped it from dissolving because one time when i was at my friends house me and him were eating jello but he dropped some in soda while he was putting it away and then the next day (24 hours later) he called me and said bro i left jello in my soda

I did my research and the only thing i found was soda fluffs witch use marshmallow fluff so i had to use a mix of the soda with some  welch's fruit jelly snacks i had left over from halloween it sat there for days and i now know what happened.the gummies absorbed it and grew just like the marshmallows if you want more proof search up sprite gummy hack. So in conclusion the gelatin was the problem in the experiment 

My question was:how fast does a marshmallow dissolve in soda

The answer to my question is:  no it won’t even dissolve in soda because of the gelatin inside of the marshmallows  

My hypothesis was correct because:

OR

My hypothesis was incorrect because: of the gelatin inside because it won't dissolve in soda 

All in all it was a fail because of the gelatin because gelatin will not dissolve it absorbs the soda that was a key component I forgot while doing the experiment that could have helped before so i conclude that this was a big fail
