When your birthday falls seven days after Christmas you often get "the shaft," as Earl calls it. I can see why he's mother struggled for 20 years, because I too find it hard to think of additional things to get him aside from his Christmas gifts and even harder to find the money to get anything additional since there isn't a paycheck between Christmas and New Year's. That being said, let's not judge me for spending only $5 on my husband's birthday, allright?
I came across his present late one night while I was finishing up Christmas shopping. I laughed to myself and pulled out my phone to take a picture of it to send Earl and thought, What am I doing? I should really just get this for his birthday. So I did. I mentioned it to my sister and she jumped on board to have a mini-themed birthday.
Earl likes the show Mythbusters and I must say that there probably aren't many episodes that I haven't watched with him. So that's why when I saw this Mentos Geyser Tube I had to have it.
My sister's contribution was this cool shirt:

I so wish that you could see in the video the full extent of this experiment. The trees in the back make it difficult to see. This Diet Coke geyser came hilariously close to us and we were not expecting it. Enjoy it anyways--listening to my sister and me snort and laugh should be entertainment enough. On a side note, I couldn't convince Earl to put real pants on for this video--he was having an extremely lazy birthday--I think he got off the couch twice in seven hours. But, hey, maybe I will feel the same why when I'm as old as him!
