In The Legend of Zelda: Tears of the Kingdom, the Morok Shrine can be found just west of the Sahasra Slope, which is east of the Floret Sandbar.
Enter the shrine to begin the A Bouncy Device challenge. Once inside, head forward and stand on the launching concrete to reach the higher ledge. On this ledge, stand on the spring then hit it with a weapon to be launched up again.
Glide to the next level. Again, stand on the spring then give it a good whack to launch up into the air. Glide to the right to find a small ball on a pedestal. Angle the spring between the slanted concrete slabs then place the small ball on top.
Give it a good whack to launch the ball across the way (and hopefully into the pit)! If you got a whole in one the gate revealing 2 springs will open. If not just put it in the pit yourself. Either way just glide back to the level with the ball pit. Grab the springs and stack them on top of the spring near the wall.
Use it to launch really high up. At the top, you’ll see the altar and the level below you can find a chest containing a Sneaky Elixir. After you grab the chest glide down to the stacked springs and take them up to reach the altar where you can grab the Light of Blessing.
