Defends against invaders

Every kid, at some point in their life, wants to keep others out of their room and be alerted to someone's presence. Whether it's an annoying sibling, a pet, or the reptilian overlords from planet Zargon. This laser tripwire kit can help them to do just that! With the added benefit of teaching them valuable STEM skills (which will help them overthrow A.I. after A.I. overthrows the reptilians.) So if you want your kid to build better, grow smarter, develop confidence, and complete fun projects- then why not start with this straightforward and fun project? They can feel like a spy and an engineer all at once.
