An explosion card at Back to Basics

It's time for our new challenge at Back to Basics and this time we would like to see an explosion card. If you haven't made one before, or don't know what they are, there's a handy You Tube video here that explains how to make one.  They are a fun card to send as the inside opens out to be bigger than the outside, leaving the recipient puzzled about how that happened!

 Here is the outside of my card....

 ...and here is the inside.

and here I've combined the photos so you can see inside and outside together.
