Continuity mistake: While the four parents are atop Adam's chest of drawers, the red Britannica Junior Encyclopædia behind Adam's Sharkruiser has its spine facing out, and we see it's volume 16. However, when Wayne, Gordon, Diane, and Patty are seated inside the Sharkruiser and begin to take off down the track, the Britannica behind them is now volume 20. (00:30:20 - 00:32:15)
Revealing mistake: While Wayne, Diane, Patty, and Gordon are in the laundry basket, Adam and Mitch carry that basket upstairs. When Mitch says, "I bet my parents wish I didn't have a medical problem," the camera turns to follow the boys as they walk up the stairs, and the left wall (with striped wallpaper) of the staircase is missing to accommodate the camera filming from that angle. It's visible again when Mitch says, "And I feel fine." (00:35:35)
Continuity mistake: In Adam's room, the yellow Hot Wheels track with the parked Sharkruiser, that is set atop Adam's chest of drawers, repeatedly alternates between having an extended track that continues to run under the books, or having an open track end in front of the book that lies flat on the chest surface. (00:30:05)
Continuity mistake: When the group is in the toy car, they freak out when they see a bulldozer running down a ramp about to crash against them. The problem is, all the front shots of them show that they left the ramp behind and the bulldozer had already crossed the track.
Revealing mistake: After the toy car crashes, the group falls down a hole, but their clothes don't react to gravity, revealing the green screen trick.
Visible crew/equipment: After Holly comes over with the CDs, sour cream, and bubble machine, Jenny then shuts the front door. When Jenny walks toward the camera, just as this shot begins to transition into the next shot, we can see the green T-mark taped to the floor, and a bit of the red T-mark as well, where the two girls stood a moment before. (00:38:20)
Revealing mistake: When the group is riding the toy car, in the wide shots of a real toy car, they disappear.
Visible crew/equipment: When the kids are making their volcano, for a split second, a crew member's hand is visible placing the balloon in place. (00:34:07)
Continuity mistake: Before the cockroach scene, Wayne finds a pin and walks away from the group. An instant cut later, the group is suddenly closer to him and also closer together.
Continuity mistake: Wayne breaks the second cockroach turd while there's a round black object behind. When the cockroach appears, the shot changes to a panoramic view, and the object vanishes, only to reappear in the close-ups.
Revealing mistake: While Patti and Diane talk next to the spider, in the close-up shot, the web becomes a thick white rope that has nothing to do with what we see in the wide angles.
Answer: Epoxy resin is sometimes sold in two seperate tubes. You have to mix the contents of both for the epoxy to harden into plastic. It also shows how weird he is, as epoxy tends to smell pretty foul.
