Hi all. Please can someone assist us with a project which ds has for this week for school. He has to make a mould (for a chocolate) using plastic which must also be insulated keeping the chocolate from melting and strong enough so it doesnt get squashed.
The whole day yesterday was spent trying to melt a plastic according to the brief from school. They were told to submerge a piece of plastic (no 1) then when its warm quickly until it softens then place into mould to shape it. Well every type of plastic we tried just curled the instant it was dropped into the water. We used all different type of plastic, (no 5 didnt even soften). Googling hasnt helped at all, they just say to melt it directly on top of double boiler, but the instruction was clear that it the plastic should be submerged in boiling water..
Typically dh is working away for 2 weeks so i cant even ask him for help.
Has anyones dc had a similar project to do and can offer some advise please?
