Hi everybody! I am Density and I am 14 years old. I am a big fan of instructables and Star Wars so this time I will show you how to make a R2-D2 bicycle and skateboard helmet. You can change the colour of the paint to make the helmet look like R2-M5 or R2-D5. I suggest you read through the instructable before you begin so you can see what to do and get a better understanding. I hope the instructions are simple and easy to understand. Enjoy and have fun.

These are the materials you will need to make the R2-D2 helmet:
– Bicycle or skateboard helmet
– Blue spray paint
– White spray paint
– Silver or light gray spray paint
– Masking tape
– Sandpaper or file
– Cloth
– Black permanent marker
