ULAB Scientific Conical Polypropylene Erlenmeyer Flask 1000ml Narrow Neck with Screw Cap, Molded Graduations, Pack of 2, UEF1003

I bought these as part of my son’s scientist Halloween costume. They were a little bigger than I expected, but they worked great. I was able to add slime to make it look like a real experiment, and the screw top prevented anything from spilling out. The best part was no worries about glass shattering as this is a durable plastic material. Very happy with purchase, and shipping was very quick.

So the plastic conical flask worked perfectly for our experiment, even if it failed. It was also very easy to clean to try again.

The best homemade bong blank there is easily worked with with common tools a wide base pretty much prevents tipovers this is the best bong here ever going to have
