Excited? No not at all.
We played pin the star on the rocket.
Then the kids made space telescopes (poked holes into a piece of paper stuck onto a cardboard tube) and decorated paper bags and party hats with stickers and twistable crayons.
Soon followed by the gobbling of the cake (and all those lollies hiding inside the rocket's dome).
We had an indoor treasure hunt for the silver painted moon rocks which we then decorated with googly eyes and marker pens, instant pet rocks to take home! So in the end the fact that it rained wasn't really a problem after all.
