Warning - Choking Hazard

Excellent skill for eye-hand coordination

These arrived just in time for my daughter's second grade groovy party where we tie-dyed shirts. I had them use the pipettes to distribute the dye instead of squeeze bottles, and their fascination with how the colors blended and absorbed into the fabric was an excellent science lesson. Many schools wait until children are older (fifth grade and up) to introduce children to science equipment, but I think pipettes are one of the most useful skill-builders around for younger children. It does take a little practice for them to get the smooth motion of squeezing and moving the pipette to extract and release liquids, but it becomes powerful when they get it right! I've used them with kindergarteners to work in their science labs for just about everything where we need a little liquid --- and where the old-fashioned eye droppers are pitiful to use -- with satisfying results. Great product!

Great product

Very practical, so many uses, and for younger kids, you may experience who has developed already a good eye-hand coordination and a "fine-touch" ability.

Plastic is really thin

These are great for the money, but I am using them with preschoolers, and they are just too flimsy. I'm sure if I were using them with older kids, there would be no problem.

Great Value!

Great size for students to use. Great bubble makers when cut! Thanks for the idea!

Good stuff.

We used the pipettes as bubble blowers. They worked wonderfully.
