Check This Out.

This is a Pyrex chemistry tube used for chemistry stuff. My neighbour was throwing a ton of stuff out and so I though this might come in handy.

1 7/8” inside diameter by 3’ so I don’t think I’ll ever run out of length.

It works like a charm right out of the box.

I’m stretching out to 7 3/4” immediately after about a half hour. No idea what the pressure is because I use oral suction via the tube.

Great stretch though.

Is it glass?

It is just very awkward to use because of weight and length. If only it was ⅓ of that length. For myself, I don’t think I would enjoy wielding that that thing around.

It’s Pyrex, which is a special type of heat resistant glass used in science experiments involving heat.

It’s actually quite light and given the length of the tube, not awkward to use at all.. And the price was right!

I’ve had several of the best pumping sessions ever using it with constant heat, and while it’s certainly unconventional, I couldn’t be happier.

Beaker,

Be careful that your neighbor was running a half assed meth lab and burn your wang.

Let’s hope this is pressure resistant as well. Won’t be nice if this got “imploded” with your penis inside.

I’m using oral pressure. I’m not hurcules.

I never thought about that. I did wash it with alcohol first though. .And happily no peeling and shredding skin.

It is not everyday I can get a double muppet and meth reference.

I am your loyal servant.

A-unit, since you create vacuum by mouth, do you use a check valve? (The check valve, it only allows air to be sucked out, and prevent any air to get in the tube). Regards.

No. It’s difficult enough to let air back in when fully pumped. I like to be free to go when needed.

So you sucked out the air, then close your valve, when you needed to get out you open the valve? Did I get that right?

I’m trying to make a home-made pump myself too, but it seems a little hard for me.

Mine is just a glass tube and a rubber hose.

You could use a check valve, they’re cheap.
