Freezed object loses it's collider

I’m making Hololens app. In my scene i have one cube and another cube acting as a wall. Idea is to make sparks appear when cube hits the wall. Problem is that when cube hits the wall it starts to move and “float in the air”. I tried to freeze it in the rigidbody constrains settings but when i do that the cube goes straight trough the wall.

Question is that how can i make the wall stay where it is even when cube hits it?

Make it kinematic
