Do the experiment. You will find the bubbles are still there the next day.
Quite apart from my the fact that gas dissolved in solution will be in your
'vacumn bubble' and quite apart from my own veiws on DCI being a biochemical
process inititiated by exposing the circulation to a gas interface would
someone else like to comment on how these 'vacumn bubbles' might act a
nuclei for further bubble growth?
