That wood glue used to be made from horse bones and that, yes, the horse dies. Another I had to explain the correlation between 1 cube meter, 1000 liters and 1 ton.

And one calorie is the energy needed to raise one gram of water by one degree Celsius. God I hate the Imperial system.

And that the calories listed on food are actually kilocalories.

The gelatin in Jello used to be made from horse hooves. It may still be.

How different could bones between animals be that you can't make wood glue from other animals' bones?

You can. It's made from bones and connecting tissue if animals.

There's also non-animal based proteins that can be gels and glues, for vegans.
