Kids treat deemed Bio-Hazard

A large scale security alert was issued near the town of Halle, Germany when a red, orange, and green substance was found on the roadside. Reuters reports a wide area surrounding the spill was cordoned off on Sunday, and experts wearing chemical warfare suits spent a couple of hours examining the substance.
The fire brigade assumed a worst case scenario and did several tests. The gelatinous substance did not respond to poking. It was bright in colour. It smelled sweet. It felt squishy. No one dared to tried to ignite it. One bystander thought the whole situation was "fruity".
After some investigation, a newly wed groom, who was pulled out of bed, agreed to clean up the mess. Who was the groom? What skills did he have that the fire brigade didn't? They didn't say. It may be he requested anonymity because this 'toxic' substance was no more than Jell-O left over from a party.
