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.

There's also non-animal based proteins that can be gels and glues, for vegans.
The gelatin in Jello used to be made from horse hooves. It may still be.
