Adding depth using Screw Modifier
We need to add thickness to the model. To do this, in the Modifier properties, click Add Modifier
and add a Solidify
Modifier.

Solidify takes the mesh of any geometry and adds depth to it.
You can change the thickness to your liking.

We need to smoothen our mesh. To do this, we add Subdivision Surface modifier.
Smoothening the mesh
In the Modifier properties
, click Add Modifier
> Subdivision Surface
.

Subdivision surface converts the faces of the mesh into smaller meshes and smoothens it.

Adding Floor
We can add another plane to be the floor. Click Add > Mesh > Plane
.
Make sure you are in Object Mode
now, if not press Tab
key to go to Object Mode.

We also need a ball that will roll down the slide.
Adding Ball
Click Add > Mesh > UV Sphere
.

Place the ball on the starting point of slide from where it will roll down. You can move the ball using Move
tool.

Select the ball and add a Subdivision Surface
Modifier.

We have modeled all the necessary objects, we need to apply physics.
Add Rigid Bodies
Select the Ball, go to Physics properties
, add a Rigid Body
. Type
should be Active
. This allows the object to be moved.
Under Collisions
, change the Shape
to Sphere
.

Now, select the slide, and Apply
the screw modifier.

If we add Rigid body to the slide without apply solidify modifier, the animation will not run properly.
Select the slide, go to Physics properties
and add a Rigid Body
. Change the type to Passive
and Shape
to Mesh
.

A passive rigid body remains static. Slide does not have a basic shape, so we change the Shape under Collisions tab to Mesh.
Now, select the plane below the slide, add a rigid body and change its type to passive. Similar to the slide, change the shape to Mesh.
