Tickets for the inverted house are 25. I bought 2 adult tickets for 48. 1.3 meters or less is free, but my husband dizzy and escaped as soon as he entered the house. It was a waste of ticket money. Tickets are not expensive, because if it is too cheap, there are too many people to take pictures. Hands holding things, stomping on your feet, the effect is better. See the uncle in the coffee house rubbing the table with a mop.
