Review on 8-Pack Of BUNMO Pop Tubes For Kids - STEM Toys That Foster Imaginative Play And Engage The Senses - Perfect Party Favors, Easter Basket Stuffers, And Toddler Gifts by Brian West

These kept kids (ages 1-4) and adults entertained on plane rides! They make a great sound which was an added bonus for the baby. The one drawback is they do not hold up to chewing (not surprising but good to know if you're buying for little ones) and are fairly easily squished side to side so they don't collapse lengthwise anymore. For the price I'd definitely buy again, they lasted for our whole trip, but not a forever toy.
