This is my space tool.I say this is very useful because it will help discover new things. The big cylinder is a filter that can clean the rock and find new rock dust.The filter will collect anything that seems to be scientific. The one hole that goes through the hole will be a place to put the rock then it will it exam the rock and say when its good to go.This box is not going to be very big it will be a medium size and be portable to clean rocks.The width of the box will be long. The length will be small but not that small.This is my box and i hope you can consider it. Thank you!
