This place is stupidly awesome and you'll lose hours in this place.There's 5 floors of mental illusions that will mess with your brain. One minute you'll be tall and slender until you shimmy over to the next one where you've shrunk 3ft and your entire body has condensed down.The mirror maze will leave you confused and untrusting of any shiny surfaces in the future. Don't even get me started on the spiny wheel thing! You'll be grabbing onto the bar 'cause you're convinced you're falling - completely mind messing (do not go in here if you've had a drink!)All round awesome place. If you go here during the day, make sure you go right to the top. There's an awesome view of Edinburgh up there!
