DIY Rocket ship photo booth at a space themed birthday blast off party. Use a few cardboard boxes covered in blue plastic tableclothes and spraymount a foamcore rocket ship on front. Cut a porthole in.
*Colored ice balls* Fill balloons with water and add food coloring- red and green would be great around christmas! (be careful not to let the food coloring escape!), once frozen cut the balloons off and voila! Look like giant marbles :)
