About the same. You can't really tell the difference between gasses just by looking at the balloon (unless it's floating). It will be filled with CO2, a colorless gas, just like air. It will be heavier, but not noticeably so.
Most balloons are fine, except water balloons. If you do the experiment in a drinks bottle, then you can easily place the balloon over the neck of a bottle.
Well the only materials you need is a balloon, baking soda, and vinegar then mix it in the balloon. Then it inflates. So actually you know what materials you need. :) Have fun!
a summary of a book project and other things
Adding vinegar to baking soda gives off CO2. If done in an enclosed chamber (bottle) it may give off enough gas and under enough pressure to inflate a balloon.
You put baking soda on a spoon then put it in your mouth and add vinegar. Then you're supposed to swallow the baking soda and vinegar. Go look it up on YouTube. However, there could be health risks. Caution must be taken to avoid rupturing the stomach. Allowing vinegar to contact the teeth can contribute to tooth decay.
the end solution is that the mixture starts foaming up!!
CH3COOH+NaHCO3 -> H2O+NaOCOCH3+CO2
There is no chemical reaction between flour and vinegar. However it will produce an acidic paste dough that will look not much different from an ordinary flour and water paste dough.
I predict that the baking soda will react with the vinegar violently and will produce a foaming effect and will emerge from the volcano rapidly
They look sort of like rings, or inflated pennies.
For making a volcano? When the two are added together, they cause a small explosion, making it look like a small model of a volcano is errupting like a real one.
Like a balloon.
As soon as the vinegar touched the baking soda, it started to make a bubbley substance. That over flowed, like a toilet over flowing. I thought it was goning to explode. If i could chage one thing i would try to add somthing to make a bigger explosinse.
well you will need some vinegar baking soda . you can take a model look at it and then you can make you're owe by using clay and when then clay is nice and hard you paint it. when you are done you are done you find a tube a small one and put it in the middle ( you need to make a hole in the middle so you can put the tube) Then add the baking soda and pour the vinegar and WA la! you have a volcano
Science fiction author Arthur C. Clarke wrote the story "A Meeting With Medeusa" in which a human explorer parachuted into Jupiter's cloud tops and inflated a hot air balloon - excuse me, a hot-HYDROGEN balloon - in order to observe the cloud layers of Jupiter's atmosphere. In the story, Jupiter was teeming with life, all suspended within the cloud tops. The story is worth reading.
It's really easy...just make a model of a volcano any way you want, and in the opening part, mix baking soda and vinegar to make it look like it's erupting. Red food coloring makes it more realistic...
