Which 5 exhibits at Singapore Discovery Centre do you like most?Why?

The best five exhibits that i liked are the Crisis Simulation Theatre,Little George,On Cocation Reporter,International Currency Exhibit and the Gateway.
I liked the Crisis Simulation Theatre because it is rather interesting as well as sort of a frightening.I also liked the Little George because it is very intelligent although it is sort of computerised.The On Cocation Reporter was quite funny because Miss Lee was the reporter.The international Currency Exhibit was very interesting because there were many interesting notes and currency and some information about counterfeiting.I learnt many things from the Gateway before looking at the other exhibits.
