Aim: To make a leakproof zip lock bag
Method:
1. Get a Ziplock bag
2. Fill the zip lock bag half full with water
3. Seal the bag
4. Get your sharp pencils and puncture through the ziplock bag with water
Results: Isn't my photo*
Discussion:
The science behind this trick is the plastic that most Ziplock bags use. The plastic is called polymer this plastic is very flexible and durable. When the pencils are pushed through the plastic creates another barrier using the pencil. This means that when the pencil is removed the bag will start to leak.
Conclusion:
If I were to do something different it would be to see how many pencils that I could puncture through the zip lock bag. This was a great and weird science experiment and I would suggest this to people above the age of 12 to try this experiment out. Thank you for paying attention to my blog. :)
Thanks for sharing dear nephew. Keep up the good work.
ReplyDeleteHi Lasa, great experiment! I'm hoping yours did work and you just forgot to take a photo! I love in your discussion the use of the word polymer- great science word. Only thing to add would be to describe what the word polymer means? Then other people who are reading this will know as well. But otherwise great blog, keep it the great work!
