Product Description

Show off your latest science experiments with this collapsible test tube rack!

Recommended for children ages 3 and up.

Add in some of the sturdiest test tubes ever. Large Plastic Test Tubes are leak-proof. Large Plastic Test Tubes feature caps that easily twist on and off, making the test tubes shakeable and unbreakable, even with liquids inside!

These come from a bottling industry. At the bottling plant, the blanks or preforms (tubes) are placed into a vacuum mold and heated so they soften. Hot air is then blown into the tube, stretching the warmed plastic to 40 times its original size to become a 2-liter soda bottle. When the plastic cools into the shape of the mold, the bottle is ready to fill with your favorite refreshing drink.
