Big discoveries require big tools and these are the largest test tubes we've ever seen! The clear plastic test tubes measure 18 cm (7") tall, 4.5 cm (1.75") in diameter. Each tube holds a whopping 240 mL (8 ounces) of liquid. Our set even includes a sturdy rack to help you show off your latest discoveries! Recommended for children ages 3 and up.

I couldn't make do with only a few so I ordered more. I used them with "hot ice," and now, most recently, filled several with mineral oil and iron shavings with a cow magnet. Fascinating to shake and watch.

They were almost perfect for what i needed them for. Big tall and comes with a stand. the reason i gave it 4 stars instead of 5 is because it doesn't say whether of not they are microwave safe and what kind of plastic they are. If they are pvc then microwaving them can let off harmful fumes.
