Cup has enough resin in the bottom, that if you mixed a bit to much hardener, the reaction would be hot enough to melt a plastic party cup easily. Lucky for you, normally by the time the cup is hot enough to melt, the resin is hard enough that it wont run and puddle causing a huge mess.
Yeah this stuff is definately exothermic. When I picked up the cup it was extremely warm. I did go a bit nuts with the hardener the first round. First time doing a project like this, so learning the materials takes some time. Super melting cups is now something I will be more careful of haha.
