Making Bubbles!

[garrym1983]

Hi, i have a pump and some airline tubing and im looking to make some bubbles!!! much in the same way that a long airstone would do. Ive pierced the airline in several places along the tubing but im wondering what do i use to block off the end of the airline tubing?? Probably an obvious answer but cant think what to do!!

Thanks

My pump has 2 airlines but I only use 1 in the tank. In the tubing that's not in the water I have plugged the end with a metal screw. I wouldn't advise using metal if it's going in your tank though, perhaps a plastic screw or some cork?

silicone will plug the tubing.

Not sure whether its very safe for the tank but maybe blue tack? Try googling it or some1 on here may now. Or the tank safe silicone they use to seal the joins on the corners probally a safer option lol
