The Together Forever Tester is a machine created by Mina Beff for Trina Riffin to use as her science project at the Science Fair in Inn Err Face. It shows how long a couple of people would last from not-ever to forever-ever. Trina wanted it to show that Nick Mallory and her would be together forever. Mina changed the machine so that it would show together forever no matter what, so Trina wouldn't be angry if it went against her wishes.
The Together Forever Tester stands on one metal leg with a black base. The main body is red with a darker red panel with symbols representing the together level of the couple holding the two petruding black handles. On the top of the machine is a rainbow, two hearts, and three stars which light up along with the faces and hearts on the panel.
