I'm interested in the milling machine, but probably I'd like to improve that! ;)
Earthquake Drill is a great and it helps the students to learn about the best ways to be secure in case of an Earthquake hit their area. It is especially good for the schools that are in the dangerous area so that students will come to know about it and will do the necessary steps in case of emergency situation.
Very efficiently written information. It will be valuable to everyone who uses it, including myself. Thanks
