We went to Costco and purchased 100 boxes. We went to Lowe's and purchased spray paint.
We put them all together and weighed them (with rocks, pennies, nuts) so they would stack without blowing over in the wind. Then we taped them together and spray painted them. It was about 5-6 hours of work with all 4 of us working. I was most proud of the TNT blocks. I used a piece of a pizza box to cut out a stencil to writeTNT.
They had fun with the blocks and built a structure that they could go inside.
After they played with the blocks, they had lunch and cupcakes. Cheese!
Then played Minecraft on the computer and on the Xbox.
The party was a great success, and now they have Minecraft blocks to play with all summer.
