On Thursday 6th May Room 5 did our post-test science with jaffas and water. This was a fair test because we used hot water in each flask. We put the jaffas in at the same time and had a little bit over 100 ml of water. We left it overnight and it still had not dissolved. The chocolate was stuck to the bottom of the flask. It took 11 minutes for the shell to crack off the chocolate (for the small jaffas). The best part was when the white and red shell's cracked off the chocolate.
