So helpful... Than you!

Excellent video! Loved how you showed the experiements that were done, and the memory tips! And the very thorough exploration of each stage. The best video on this I found. Thank you!

Very educational!

Great video! But now I really want to eat lucky charms....

Exellent presentation, thank you.

I love how you broke this down with slides and verbal explanation.

I love the way you broke down each stage into a simplistic form real easy to understand.
