Halloween Fun with PVC Pipe!

Build a Creepy Black Widow Lawn Spider with FORMUFIT PVC

Halloween is just around the corner, and what better way to celebrate than with a DIY project that’s both spooky and fun? Using the FORMUFIT PVC Spider Pumpkin Plan as a base, you can create your own Black Widow Lawn Spider — a chilling decoration that’s perfect for your yard, porch, or Halloween display.

This project is a great hands-on activity for kids and families. With just a few PVC fittings and some paint, you’ll have a durable, weather-resistant spider that can be reused year after year.

Project Modifications

To give this spider a more sinister look, a few changes were made to the original design. Instead of using 1 in. PVC pipe and fittings, this version uses 3/4 in. pipe and longer leg segments, creating a sleeker, more lifelike appearance.

Materials Needed

• 4 × 3/4 in. 3-Way PVC Elbows (Black)
• 4 × 3/4 in. PVC Tees (Black)
• 8 × 3/4 in. 45° PVC Elbows (Black)
• 8 × 3/4 in. 90° PVC Elbows (Red)
• 8 × 3/4 in. External End Caps (Red)
• 18 × 3/4 in. Furniture Grade PVC Pipe (Black)

Pipe Cut Lengths

• 8 × 24-inch pieces
• 8 × 20-inch pieces
• 2 × 12-inch pieces
• 14 × 2-inch pieces

These cuts can be made easily using a ratchet PVC pipe cutter or a simple hacksaw. Once assembled, the glossy black Furniture Grade PVC won’t fade or become brittle in the sun like standard plumbing PVC, making it ideal for outdoor use.

Finishing Touches

Grab a large pumpkin (under $10 from most stores), spray paint the body black, and assemble your spider’s legs around it. In no time, you’ll have a giant Black Widow Spider that’s both creepy and eye-catching — perfect for Halloween night!
