Valentine’s Day Warning: Chocolate can kill. But how much?

February 8, 2026

With Valentine’s Day approaching Mathspig has reposted this warning.

Chocolate contains a chemical called Theobromine. This alkaloid ( other alkaloids include cocaine, nicotine, caffeine, and strychnine) can kill humans. More info Wired Magazine.

How much chocolate is too much?

Firstly, the darker the chocolate the more Theobromine it contains.

According to About Chemistry based on the highest possible toxicity:

* VetmedicineCooking chocolate contains 8-10 times the Theobromine in Milk Chocolate.

According to Wired large doses of theobromine may cause “nausea and anorexia ….. sweating, trembling and severe headache.”

The Royal Society of Chemistry notes that chocolate does not contain caffeine, but theobromine induces similar symptoms.

LD50 for the lethal dose for 50% of the population for Theobromine is:

1000 mg/kg 0r 1gm/kg of body weight in humans

Death by Chocolate for real if this egg fell on you!

March 26, 2024

According to The Guinness Book of Records the largest chocolate Easter Egg is still the one that went on display at Le Acciaierie Shopping Centre, in Cortenuova, Italy, in 2011.

 Egg Weight   = 7,200 kg  = 15,873 lbs = 7.9 US ton

Height = 10 m =  34 ft

Circumference = 19.6 m = 64 ft

The sugar content for easter eggs is: 55-65% by weight

So we will assume the sugar content of the giant egg was in the middle:

60%

The weight of sugar in the giant egg equals:

How long would a tiger take to eat your math teacher?

December 30, 2023

The answer to this question is not ‘Toooo loooong!!’  It can be answered approximately.

According to a DREAMWORLD fact sheet Bengal tigers eat between 4 and 5 kilograms of chicken, horsemeat or kangaroo meat five days a week. To imitate their diet in the wild, Dreamworld’s tigers – Java, Jaya, Kia, Khan, Nika, Pi, Raja, Zakari and Akasha – fast on bones twice a week.

Death by Caffeine: The Maths  Part 1 METRIC

Death by Caffeine: The Math  Part 1 USA UNITS here.

The lethal dose for caffeine is about 150 milligrams per kg of body weight. While the average person’s caffeine consumption is around 200 milligrams a day, the Mayo Clinic advises against exceeding 500 to 600 milligrams per day.

This work titled Timing is Everything is by street artist ABOVE in London.

You may want this much energy but be warned, energy drinks can kill.

It would take a ridiculously huge number of ANGRY WOMBAT energy drinks to kill a 14 year old weighing, say, 48 kg. Nevertheless, some kids are more sensitive to caffeine than others and then much lower levels of consumption of energy drinks can be fatal.

I Can’t Sleep: Caffeine Math Part 3 USA UNITS

I Can’t Sleep Math: Caffeine Maths METRIC HERE.

Sensitivity to caffeine varies for individuals, but in healthy adults the half life for caffeine is approx 6hrs meaning your body eliminates half the caffeine you have drunk in 6 hrs. Ref: Caffeine Pharmacology

Caffeine interferes with sleep. One study found that consuming caffeine 6 hours before bedtime reduced total sleep time by 1 hour.

Caffeine content sources Caffeine Content Data Base

Street art by JEKS, South Carolina

The Half life equation is an exponential function.

The Mayo Clinic advises up to 400mg Caffeine a day for adults, which would be;

10 black teas

7 instant coffees

4 cappuccinos

2 dark roast brewed

less than one cup of Black Insomnia Coffee.

Approx half this amount of caffeine for 14 yos.
