Gravity cake

Happy birthday! 

My son just turned 10 and here's the best birthday cake that I decided to make that makes the buzz on the web and makes heads turn on it's sight... The GRAVITY cake!!!
My kids loved it, hubby thinks I'm a genius, friends were amazed and there were even people that took photos of it :))))
Special thanks to both of my children that helped me doing it, and my apologies to my daughter that I underestimated her capabilities as she has proved that often she is much better than me ! Kiss to hubby for the support, as always, to my crazy ideas.
So, let's get back to the cake. Procedure goes like this...

1. To start, you can use as a base, your favorite recipe for a cake. In my case, this was my chocolate cake recipe that I just love for birthday cakes. 
2. You can cover it with melted chocolate that you have added some fresh cream in it. 
3. Glue using chocolate, biscuits like the Cadbury fingers, almost all around it but leaving a small part uncovered. The most interesting part follows...
4. The magic is based on a hidden flexible straw that has m&m's on it, using melted chocolate as a glue. This is actually the most delicate part of the whole procedure. Start by covering one part of the straw, put it in the fridge (not the freezer!!! m&m's lose their color otherwise) and then repeat on the other side. 
5. Glue the rest of the m&m's simulating the falling part and finish by adapting the straw in a wooden skewer that you have put before in the center of the cake.
6. Cover the straw ending with the empty bag of the m&m's and let all overnight to harden.

The next day, just admire the result and feel proud under the envy look of the children and even adults around you :)  Isn't it great?
