PourTots
Two cups of water look just the same. Pour one into a tall thin jar. Which has more now? Make a guess, then pour it back and see. Three pairs of jars, a glug in the speaker, and then: try it at the sink with two real cups. Ages 3–5, with a grown-up.

Meet the cast
PourTots's friends live round the water table. Glug pours to check, Lanky is tall and thin and looks like more, Squat is short and wide and looks like less, and Pairly carries two same-size cups so the check is fair.
Glug
pours the water back to check, because looking is not the same as knowing
Lanky
A tall thin heron - water in a tall thin jar stands high, so it looks like more
Squat
A short wide toad - water in a short wide bowl stands low, so it looks like less
Pairly
An otter with two same-size cups - pour both into the same cups and you can see which has more
