Plasticine can be used to model aerofoil shapes for experiments, but its weight may affect lift performance. The discussion highlights the use of plasticine as a substitute for polystyrene in low-tech wind tunnel experiments. While results have been obtained using plasticine, there is uncertainty about its acceptance as a valid material for aerofoil testing. Participants suggest seeking advice from an aerospace engineering forum for more specialized insights. Overall, the project on investigating lift with different shapes is recognized as interesting and worth pursuing.
