The Museum of Illusions in Tel Aviv is charming and interesting.
The place is small and suitable for all ages. You pass through exhibits, each of which explains in different interesting ways issues of balance, optical illusions, mirror tricks, deception of the mind, perceptions of height and depth, and more.
We spent about an hour there.
After, you can stroll the Tel Aviv port (where the museum is located) or the nearby Joshua Gardens Park.
