Had a Science Birthday Party for my son, specifically Chemistry themed party. Made a periodic table birthday cake, which I have posted already. I made the birthday banner with the element names and atomic number for each of the letter of 'Happy Birthday'. Added few images of beakers from the internet. And I had arranged for some cool Science experiments at home. I was actually skeptical whether the boys would like it..but they just loved it!! They had absolute fun and that's what I wanted!!
