Some parents buy tickets and bring kids to the movie
Some watch Discovery Channel on SKY
Some go to the Gardens etc

Here is an idea of having unusual ad cute show for kids in your own home:

Watch "Butterfly, emerging from pupa" and then release it into the nature

How about $15-20 for a couple of pupa's attached to the branch in a small vase? (it is like complete set...)

After a lot of efforts and saving caterpillars from the osps my wife now have about 20 Monarch pupas under the mesh.
She has released already 2 butterfly watching them gracefully spreading the wings (takes time) and then flying away.

The rest of them about to emerge into Butterfly in the next few days.

Just testing the idea. She has already showed one event to a lady who found the event "very special".
