Exploding wood effect

Try something like this

1. Put the ball on it's own layer

2. Take a wood layer and use the liquify filter to bloat the wood then add a layer mask with a jagged hole

3. Now make a new layer - with a copy of the original floor rotated and masked into shards. Add a layer style with an inner shadow and drop shadow.
Also add a curve to lighten slightly compared to the original floor.

Make this layer into a smart filter and add a radial blur (set to zoom)

4. Repeat step 3 two more times (each time rotating the wood and creating different shards)
For each of these additional layers use an increased amount of radial zoom blur and also use curves to make them lighter

Hope that gets you started
