In the movies Honey, I Shrunk the Kids and Honey, We Shrunk Ourselves scale models were used to make people look small. For example, a giant ant was created for the movie Honey, I Shrunk the Kids.

In the movies, the inventor of the electro-magnetic shrink ray was played by Canadian actor Rick Moranis. He’s at it again in the movie Honey, I BLEW UP the Kid, but this time he creates a machine that turns his toddler son into a giant who strolls through Las Vegas. How would the scale models used in Honey, I BLEW UP the Kid be different than the scale models used in the shrunk movies?
