As many of you heard or experienced, when inventing skill reaches 5 or 6 you can start detonating objects.
Well I did some experimental work, and one involved the Knack Family, my sim was able to stay with the Knacks for the night, My Sim woohoo-ed their daughter Julienne and then fell asleep, her parents was sleeping in the other room,
So... I woke up in the middle of the night and sneaked into her parents room and set a bomb on their bed, then my sim ran out of the room and waits for the explosion. The mother woke up and left to the bathroom while the father still sleeps... 3...2...1... BOOM!!!
Nick Knack survived the explosion, lost his clothes and his hair sticking up and covered in dust/debris... When my sim talked to him... It says "Nick Knack is Very Angry with you"
Really funny :3
Julienne gave birth to my sim's son that very same night (after the explosion)
