One of the most fun museums I've ever been to has to be Explora! (yes, it has exclamation points in its name), located on the west side of Albuquerque.
It's an interactive museum--all of the exhibits are things you can touch and play with.
Most of the topics are science and technology, and the different exhibits are fun to play with.
Want to learn about aerodynamics first-hand? Try and float various items on a stream of air!
Sound waves? Light? Gravity? Learn about all of these while interacting with objects and instruments.
Even better, Explora! has special events like Adult Night. If you've ever been to a science museum and watched kids play with the children's exhibits, trying hard not to move them out of the way and play with the exhibits yourself, you're in luck--this is exactly what it's for. We had a blast making giant bubbles and playing with blocks without worrying we were going to get kicked out.
If you want to have a fun day out, I totally recommend checking out Explora!
