Things were always appearing or disappearing on Bewitched and most of the time poor Gladys Kravitz was there to witness it. Can you recall an episode featuring something like this?

In Season 1 when Samantha and Endora first go to look at the house, they each take turns adding a nice green lawn, shrubs, trees, flowers, furniture, drapes etc. and of course Gladys is the only one to see it before it gets zapped away.

On a Christmas episode, little Michael doesn't believe in Santa Claus so Samantha gets out her broom and flys them to the North Pole. And Gladys sees them from her window and when she calls for Abner to look, of course they've vanished.

Endora zaps up several different types of red lights in Samantha's living room and Gladys peeps in the window and sees them, & when she returns with Abner, they're gone.

Endora Moves In For A Spell-Season 3. Endora and Uncle Arthur have a falling out over who is to live in a house across the street. Gladys wants to find out about the disappearing and reappearing house, much to Sam and Darrin's dismay!

In Season 4, Gladys saw Aunt Clara turn the neighborhood into a harbor when she wanted to go sailing. Of course, Sam changed everything back by the time Gladys got Abner to look out the window. :lol:

At the end of the same episode, Aunt Clara ended up stuck on the roof when her powers went back to Endora. Sam appeared and made them both vanish (back inside the house, I presume). Of course, Gladys was on hand to witness this, too. :lol:

Endora zaps up a bunch of fishing equipment for Darrin and of course Gladys peeps in & sees it but when she takes a second look, its gone.

wasn't there an episode in season 1 or 2 (I know because it was in black and white) where Samantha or Endora zapped a pool into their back yard? And of course Gladys saw it, but when she got Abner to show him, it was gone when they looked.

That was in the first season episode, "And Something Makes Three". Samantha was the one who zapped up the pool. Endora was not in that episode.
