Meanwhile, printing the digital images with an ink-jet printer at home brings back fond memories of darkrooms under the stairs with trays of developer, acetic acid and hypo.
Previous work at Queen's University found that prawns show prolonged rubbing when an antenna was treated with weak acetic acid but this rubbing was reduced by local anesthetic.
It is heated to start the reaction, and when it is complete the resins, residual acetic anhydride and acetic acid are wicked away from the wood, and the pine has become Accoya.
Acetic acid in the vinegar delays stomach-emptying and acts as an antidiuretic, remaining in the hung-over body longer than water, and allowing it to rehydrate by absorbing salt and electrolytes in the brine.
