Testing solvents

Today, Bluebirds carried out an investigation to find the most effective solvent to remove nail varnish. They wore goggles and gloves and really looked like scientists! First, they predicted which solvents they thought would work. They tested water, bleach, hydrochloric acid, ethanol (meth spirits) and propanone (acetone). Each group of three, were given a tile and then painted 5 lines of nail varnish on to it. The group then dipped a cotton bud into one of the solvents, to try and remove the varnish.
