I put in 11 quarters and I wasn't able to play until a couple of minutes passed what can I do?

Go to the Comet pinball game in the middle row. It plays every time you push the play button, no quarter needed!

There are workers there. You should ask them. Most games only operatd when lit up.

Talk to the staff. They are incredibly friendly.

You can always contact the person they're working on the machines and ask him if there's a problem with the game that you're playing

Go talk to the staff. They're located all the way in the back of the museum

There's a friendly staff there that can help you.

Ask the staff

When all else fails, coin return! I had a couple issues with the machine not recognizing quarters I put in. I pressed the coin return button and then re-inserted the quarters with a bit more force and the machine recognized them.
