some people considering buying these might want to know that if you fill these to the brim they hold about 20ml. I got these for a costume but other people might want then for actual experiments and might need this information.

I purchased these test tubes to hold rolled up invitations to a "science" themed birthday party. The description listed them as 1.5" in diameter, which should have been plenty big. However, the actual tubes are much smaller. The cap is about 0.75" in diameter, and the tube itself even smaller. Had to return them. They are, however, a "typical" test tube size that you might expect if you didn't read the description.

I bought these to hold candy for party favors at a "Mad Scientist" birthday party. They were perfect for what I bought them for. I loved the fact they had a screw on cap. It made it easy for the kids to open.

Honest reviews on PLASTIC TEST TUBES W/ CAPS 12/PK

we had a science party for my 6 yr old and used this in the "goody" bags with a "sour" gummy worm inside. Could put any number of things in them but the sour ones have a sugar coating and won't stick to the sides so they slide in/out easily.

We kept a few extras b/c we like to do science experiments around here from time to time and they will be very useful.

I had planned to do a science demonstration for school and I put oil in these test tubes. 3 days later, 9 of the 12 broke. The rims broke so the caps would not go on and they leaked everywhere. It was a complete waste of my money and ruined the demonstration I was doing at school.
