Wow! This homemade high powered laser device is really cool. Although to do it is a little bit confusing and might be difficult but I like the end result.
This laser can lights a match and pops out a balloon. Watch the video and see how he built the laser using the materials that you can find at your home.
Interesting isn’t it? 
Kind of dangerous if you ask me..
Maybe we can use it to blind someone. Ho3. Crazy idea!
