Bendy Straw Experiments

Floating Ball (4)

I have a pack of bendy straws at home, and this morning Travis and I used them in 3 experiments! Try one or all three, and see which is your family’s favorite.

Pom-Pom Popper:

For the first, poke a small hole in a dixie cup. If your cup is paper, kids can punch through with a pencil tip. We had plastic cups so I used a craft knife to make the slit.

Cut the tip from a bendy straw just before the bend. Insert the bent end into the cup’s hole and tape on.

Place a pom-pom in the cup and blow. Some good lung power can really make these jump!

Travis was so proud when he was able to do it.

Floating Ball:

The next experiment was similar, but we got a little craftier. Cut circles from colored construction paper, and cut a slit in each to the center. Fold up into cones, securing with tape.

Snip a small hole in the tip of each cone and insert the bent part of a bendy straw; tape on for extra security.

For extra fun, make them monster mouth cones! We cut out teeth and eyes from additional colored paper and taped on the features. If you want a cleaner look, use glue to attach, but Travis was eager to get to the next step of making the monster eat a silver ball!

Crumple up a small piece of aluminum foil and place just over the opening of the straw. Huff into the other end and your ball will pop and spin and dance just where the monster can’t eat it.

Bubble Valve:

The final experiment was the simplest, but still fun. Cut a tiny slit in the top of an uninflated balloon, just large enough for a straw to fit. Insert the bottom end of a bendy straw. If your hole is a little too large, ideally get a new balloon and start again. This was the last balloon in the house, though, so I taped over a small gap between balloon and straw.

Insert into a clear glass of water, then blow into the straw to make bubbles. Try and suck up to get a drink through the straw, too, which is much harder!

Travis loved that he was able to do this one, too.
