Floating wax moulds of rubber ducks

Our task is to make 5 floating wax moulds of rubber ducks using the previous plaster mould. What we did was pour wax into the mould on both sides and take the 5 best and also make sure it floats. There were a lot of errors such as not enough wax being placed into the plaster moulds, too much ridges, perfect mould but not able to float moulds. Here are some pictures I took of the processes.
