What you'll need:
Stiff plastic straws
What to do:
Confused with the title? How is it actually possible to poke potatoes with straws?
Well it’s easy, and here's the trick.
You hold a straw by its sides and poke the potato. What happens? The straw goes through a small part of the potato.
Try again, but this time, cover the top part of the straw with your thumb and you can see the straw go through a bigger part of the potato.
What happens here? When you cover the top with your thumb, the air is trapped inside the straw, which makes it stronger, unlike the first attempt which pushed the air out.
Have fun poking potatoes!
