hey guys
im in year ten and for my srp (Student research Project). ive decided to see how much gas comes out of various chemicals.
what ive done is take several glass coke bottles, fill them half way with different liquids, then put a balloon over the top and wait a few hours. after that record the results (ie, if the balloons standing up straight or not). my problem is ive tried milk, wine vinegar.....on and on but i cant seem to find anything that actually does anything.
does anyone have any ideas as to what household chemicals i could use?
thanks,
