Do you know how to put a skewer through a balloon ? It’s surprisingly easy and a great science trick! If you’d like printable instructions for this you can find them with my other science printable experiments.
What you’ll need to push a skewer through a balloon
Washing up liquid/Dish soap
Skewer – take care. These are sharp
Balloon – experiment with different sizes and shaped balloons
First, we tried using Vaseline rubbed on the skewer and the balloon, but although we could get the skewer in, the balloon always popped on the way out.
We tried again using washing-up liquid, and it worked!
You need to pierce the balloon through the bottom and top, where the rubber is thickest, and then push the skewer slowly but firmly into the balloon.
Top Tips
Poke the skewer through the part of the balloon where the balloon material is under the least strain. This is generally the two ends.
How does it work?
Balloons are made up of long chains of molecules called polymers, which are elastic enough to allow the balloon to stretch. The dish soap reduces surface tension on the balloon, helping the skewer pierce it.
The polymer chains of the balloon close around the skewer, which stops the air from escaping and allows the balloon to stay inflated.
Try piercing the ends of the balloon first, as this is where the balloon is under the least strain and so strongest.
Where would you pierce the balloon if you wanted it to pop?

that’s great – I think I will have to use this to impress the kids!
How cool is that? Balancing the skewer through the balloon. Thank you for sharing our video and your cool version of it.
Very impressive! Thanks for sharing some great ideas.
oh, my kids LOVE this experiment, we’ve done it as well! We’ve even pushed the skewer all the way through! http://blog.anportraits.com/2012/03/19/stick-balloon-fun-seattle-area-lifestyle-photographer/
Can’t wait to impress the kids with this! Xx
That is amazing! Love it!
One that my Six year old will adore, very clever! Thank you! 🙂
Ooh I remember doing this as a “party trick” as a child. You do bring back some brilliant memories!
How clever. I fear I could get through quite a few balloons trying to perfect this.
yes, we did 🙂
Great experiment!
