Lego laser pointer

first of all I'm Hungarian so sorry for the mistakes. If you want to play whit  your cat ,you can use this. Its easy so you can make this really fast ( i made it in an half an hour) its price was low exactly 1650 Hungarian fornits ( 9  USD). in the next step I only wirte "some Lego block" because  it may vary.
