Learning Resources Jumbo Test Tubes, 7 Pieces

Worked great for my sons science experiment for his science fair. He used each test tube to hold different mixtures to see what crystal would grow.

Purchased this for our 4yr. old grandson who loves to explore & experiment.

Great product. Super size and super fun

Great quality. Very sturdy easy for younger kids to handle.

we loved our test tubes we have made lava lamp and sensory bottles with them so far. We are look forward to other experiments that we can use the test tubes .

These tubes are a great size and work perfect for my use(which is small groups of kids/classroom like setting). The company has also been wonderful. I had some tubes crack at the top and company sent we new ones right away. I had replacement sets within 2 days of my request!!

Use these to dissolve bath color pellets, and mix all kinds of colors, teaching how primary colors can combine to create new colors, teaching about how volume changes and concentration changes affect opacity. Large size, can screw caps on so tightly that toddlers can't open.

Lids are too loose and will Leak even after tightened. Have had trouble getting them clean too. Love the stand. Great size for hands too. Good but don't use anything that will stain.
