Summary: Since I was a little kid I always wondered what it would be like to swim in a pool of Jello. Turns out it is really difficult. We heated up the Gelatin in 55 gallon drums and then used gravity to put that jello into the pool.

They are soft-



I make videos like this once a month all year long while supplies last:

    Is it possible to adopt a uncle?

    • alannah seaton says:

      +The Major they literally said it in English??

    • Mad Petal says:

      +The Major clearly you don’t understand anything about the language, mate. Uncle begins with a vowel, and as such ‘an uncle’ is grammatically correct. Since you said ‘you bloody English speakers’ I will assume that English isn’t your first language and it may be a good idea just to brush up on some basic grammar.

      Showered Woofer
      You always put an an before a vowel. Here are some vowels. A, I, O, U.

    • that one weirdo says:

      The Major i won’t be rude because maybe you speak a different language, but the word an always goes before a vowel.

    • Showered Woofer says:

      that one weirdo english is not my first language so thank you.

    The real challenge is how you’re going to clean that up.

    Gelatin powder is food. It is made from boiling bones.

    • alannah seaton says:

      Yes, but you can’t just eat it straight.

    • Jannik Heidemann says:

      It is not ground up bones. Gelatin is a molecule that can be extracted from almost every part of an animal or human.

    • malenotyalc says:

      Historically it was bones ground up and boiled – and the gelatin was skimmed from the top of the broth – and it was then dehydrated and ground into a powder.

      You can also make it from other sources like algae – but it is not called gelatin then, but agar agar.

    • malenotyalc says:

      No matter how you slice it (make the gelatin), it is food that is regulated by the FDA when sold in powder form alone must still list the nutritional contents. I provided a link above to said nutrition facts.
