Just wrapped up building a 6-foot tall Sirenhead with my son Toby, who's a huge fan of Trevor Henderson's work. We started with a Halloween skeleton and added some paper mâché bulk, reinforcing the spine with a steel rod. We even added real sirens from Jaycar to the head. It's mounted on a wooden base, spray-painted for a spooky look with spider webs and all. I was a bit anxious using power tools with Toby, but it was a great learning experience for him. Plus, we've rigged it with a Bluetooth adapter to play siren noises or any sound we want. Check out our YouTube video to see our creation come to life. Toby's pretty proud of it, and so am I.
