We had to fill the small bottle, to fill the medium bottle, to fill the big bottle! We discovered that 2x250ml will fill the 500ml container and 2x500ml containers will fill the 1 litre container. We had a good time in the process!
Would you trust 3MB with a bunch of hammers, nails and saws? SURE you would because we can make awesome stuff! Asher from Learn By Doing helped but we managed to create some fantastic windmills. They actually spin, amazing!
