How to Make Air Hockey-Cardboard DIY 

I made an air hockey, which is common in amusement arcades or bowling alleys, with cardboard.
■How to Make
1. Make holes 2mm in diameter on the top plate, the distance between holes is 20 mm
2. Caulk the gaps in the box with silicone
3. Connect 3 blowers
4. Attach the base and decoration
【Material 】
Laminated cardboard (may be substituted by ply wood etc.)
Cardboard 　Blowers (airflow：3.5m3/min)　LED(as you like)
【FREE TEMPLATES】

If you reduce the size of the top plate to about 1/3, it maybe enough one blower.
Please pay attention to the power consumption of the blower and safety. Please use at your own risk.
