Hi we did reversing today here are the things we tried.
First was wood went we light the match you can not revers it.
2nd we did the chocolate it was very quick and then we taped it on the plastic plate it took awhile for it to get of the spoon.
3rd was bread my partner was scared in case it fell on the tea light. Half of it did but I just flicked it of in end.
4th was wax it melted in seconds and tried in seconds it was completely dry.
5th Ice it was melted in milliseconds and it would be reversible but we did not put it in the freezer.
By thanks for reading!!!!!!
