Learn how to build creative 2D and 3D projects with the Plus-Plus 70 pc Neon Tube. Step-by-step instructions for making neon creatures, vehicles, and patterns.

Quick answer

Start by sorting your neon and transparent pieces, then build simple 2D shapes before combining them into 3D creations like creatures, vehicles, or patterns.

Why the Neon Tube works for open-ended play

The 70-piece count is small enough to keep builds manageable for beginners or quick projects, but the neon color palette and transparent pieces add visual pop that makes even simple creations feel special. This set shines when you focus on bold, simple shapes rather than complex structures.

Trade-off: limited pieces vs. unlimited ideas

With only 70 pieces, you cannot build large-scale models or detailed characters. Instead, use the limited count to your advantage: build small, colorful animals, mini vehicles, or geometric patterns. The neon and transparent pieces encourage contrast and experimentation.

Step-by-step guide to building with the Neon Tube

Sort your pieces by color: Separate the neon colors (pink, orange, yellow, green) from the transparent pieces. This makes it easier to grab the color you need and helps you plan color contrast. Keep transparent pieces aside for windows, eyes, or accents.
Start with a 2D base shape: Choose a simple shape like a square, triangle, or circle. Build it flat on a table by connecting pieces side by side. For a square, use 4 pieces per side; for a triangle, 3 per side. This becomes your foundation. If your shape wobbles, press each connection firmly until flat.
Add a second layer for depth: Stack a second layer of pieces on top of your base, offsetting the connections for stability. Use a different neon color to create stripes or patterns. For a creature, add a second layer for the body. Offset connections (like brickwork) to prevent the build from falling apart.
Build 3D details like legs or fins: Attach pieces vertically to the sides of your base to form legs, wings, or fins. Use transparent pieces for fins or wings to give a glowing effect. For a vehicle, add wheel-like bumps on the bottom. Vertical pieces need a flat base underneath; press gently to avoid snapping.
Add final accents with transparent pieces: Place transparent pieces on top or in front of neon pieces to create glowing eyes, headlights, or decorative spots. They also work well as windows on a vehicle or bubbles on a sea creature. Transparent pieces look best when placed against a darker neon background.
