this morning we did a science experiment with a australasian snapper that was discoloured and aged. first we looked at the diferent parts of the fish, then we cut out a small portion to look at. in another one of our tests 8 of us rubed their hands on to fish then were given a chemical- baking soda, vinegar etc. we all took a sniff at their hands and waited while they doused and/or rubbed their hands with the given chemical. the rest of u made a asumption to wich would work the best. after smelling them all twice the results came out as... 1st dish washing detergent 2nd soap 3rd toothpaste 4th vinegar
