Test Tubes (set of 6)

My 3-year-old loves pouring water back and forth between these test tubes, and the plastic caps stay on securely even when she shakes them. They’re the perfect size for little hands to practice fine motor skills without spilling everywhere.

The glass feels sturdy enough for my preschooler’s enthusiastic mixing sessions, and the set’s included dropper helps build fine motor control. We’ve used them for everything from color mixing to simple sink-or-float experiments.

My toddler loves carefully pouring water from one tube to another, and so far they've survived a few drops onto the tile floor. The glass is perfectly sized for little hands to grip while mixing colors.

The glass feels surprisingly thick and durable, and the wide opening makes it easy for my son to pour water back and forth without spilling everywhere. We've been using them with our color mixing activity every day this week.

My toddler loves shaking these to hear the liquid slosh—the clear glass makes it easy to see the colorful water swirling around. They're just the right size for small hands to grip and pour into each other.

The rubber stoppers seal tightly enough that my toddler can shake them without any drips, yet they’re easy for her to pop out on her own. She loves watching the colors swirl during mixing, and the 6 tubes give her plenty to work with at once.

The thicker glass and snug stoppers feel much sturdier than the thin plastic tubes we had before. My kid actually enjoys the pouring practice more now that the tubes don't tip over as easily.

My toddler loves using these to mix colored water and pour between them—the clear plastic makes it easy to see the swirls. The included stand keeps them organized during messy play.

I use these for propagating my spider plant babies, and they are the perfect size for rooting cuttings in water. The glass feels thick enough to survive a drop from the counter, which is a huge plus.

I was pleasantly surprised by how sturdy the glass feels compared to cheap options I've used before. The uniform diameter makes them easy to store side by side in my rack without wobbling.
