Leaping in Without a Net - November 18, 1958 - S2-E19
Continuity mistake: When Sam and his sister are on the trapeze and she does a double and he catches her you can see that the bar she jumped from is not moving behind her. Then when she jumps back to it, it's swinging again.

Continuity mistake: In practice, when Sam's sister tries to do the triple and he misses her, the wide angle shot shows that she is already below Sam's arms when she reaches out. But when it cuts to a close shot, she is able to almost catch his arms.

Continuity mistake: Throughout the show, the big top changes from one with many blue stripes on the ceiling, to one with a couple of blue stripes and a dark center, and back again.
Answer: Sam threw items off the raft to lighten the load, so it wouldn't sink, in doing so he made the raft less heavy. Which made easier to float with the currents, if it was heavy the raft would have moved slower and not moved so far.
Except that Al said that immediately after throwing stuff out of the boat four hours passed and it was shown that they didn't really move from where they were. They were still in the same spot. Forgot to ask this too. When Sam and Vanessa are stranded on the island, one of them, can't remember who, did something and when Al appears, he tells them that because of it, time had suddenly skipped several more hours and if the event hadn't been interrupted, they would have been rescued by a boat. So, what happened on the island that once again caused time to speed up? It seems kind of strange that time could move so quickly on the island, especially since it was still day time and it never showed any sort of changes like the sun or clouds moving.
