What Emmett Has Been Up To Lately

 Lego Mazes:  The objective here is to get the pile of gold at the end while avoiding traps such as clone troopers (or whatever they are called) and flowing lava. 

 Emmett's creation for this lego challenge round on frugalfun4boys.com which is to build a car that can go long distances -- we actually did not have enough space to give this vehicle proper testing as it traveled nearly the length of our house (with carpet in spots).  Emmett estimated that it could easily travel 25+ feet if we had the space and proper flooring. 

 But, after the challenge was complete,

Emmett felt the need to modify his creation with weaponry and such. 

This is Emmett's "experiment".  See those crystals? 

Can you guess what Emmett let dry out to get these marvelous beauties?
