Experiment:
- Aim: To determine which brand of paper towel is the most absorbent.
- Hypothesis: I think that the v-shaped ripples on the viva paper towels will not make much difference in the amount of water absorbed.
- Equipment: 5 different types of paper towel; 250 mls of water; a tray; 50 ml syringe.
Method:
- Measure 50 mls of water into the tray.
- Put one square of one of the types of paper towel in the tray and make sure it has absorbed as much as I can.
- Remove the wet paper towel from the tray.
- Measure the water remaining in the tray and subtract that number by 50 to get the amount of water the paper towel absorbed.
- Repeat steps 1-4 with the other types of paper towel.
- Convert all the results into a column graph.
Results:
| Brand of paper towel | Cost of paper towel | Water left in tray (ml) | Water absorbed(ml) |
| Coles smart buy | $0.91 | 29 | 21 |
| Safe | $1.16 | 29.5 | 20.5 |
| Thick & Thirsty | $1.36 | 26 | 24 |
| Handee ultra * | $1.76 | 18.5 | 31.5 |
| Viva (Kleenex) * | $1.89 | 22.5 | 27.5 |
* Brands that claim to be the most absorbent.
Conclusion:
It has been determined that the most absorbent paper towel is "Handee ultra" it absorbed 32mls of water.
Discussion:
Although "Handee ultra" is the best paper towel for cleaning up liquid, they are probably not the strongest, it would take more experiments to confirm this.
