Q

This achievement requires you to have unlocked the level set PRIMARY 3. You can unlock PRIMARY 3 by first completing a set amount of levels in PRIMARY 2 (If anyone knows the exact amount, please let me know in the comments).

For this achievement you need to complete Q.45 with just 1 drawing. To do this, create a large "r" shaped drawing on the left of the screen. Make it as large as you possibly can. When released, the drawing should fall down, propping up the tube and releasing the pink ball.
