I did google it already. However it looks like nothing I know (except that kind of corn flour we call Maizena around here - even though Maizena is a trademark - but I don't remember it having those properties).

As we are in /food/, I thought it would be appropriate to ask for some discussion about that. Enlighten me. What do you do with cornstarch, except silly experiments, puddings and biodegradable blu-ray discs ?
