A hive half full of honey logic puzzle

At the start of summer, the amount of honey in the bee hive is low. However, the bees work hard and every day, the amount of honey in the hive doubles. On the 30th day of Summer, the hive is full of honey. On what day was the hive half full?

Reveal solution

If it doubles every day, the amount of honey in the hive on any given day would have been half the amount the day before. So if the hive is full of honey on the 30th day of Summer, it would have been half full on the 29th day of Summer.

Cutting a cake lateral thinking puzzle

Two bees, Buzz and Honey, want to share a cake fairly between them by cutting it into two pieces. Buzz worries that if Honey cuts the cake, he will be left with a smaller portion. Honey worries that if Buzz cuts the cake, she will be left with a smaller portion.

How can Buzz and Honey cut and share the cake fairly between them?

Reveal solution

One bee cuts the cake and the other bee chooses which piece they will take. This will prevent whoever cuts the cake attempting to cut themselves a bigger slice.

The lying bee and the truthful bee logic puzzle

There were two bees, Apollo and Buzz. Apollo said to Buzz, “I always tell the truth”. Buzz responded, “I always lie”.

One of these statements is correct. Which one?

Reveal solution

The statement by Buzz “I always lie” is an example of the liar paradox. If the statement were to be correct, it would contradict itself (Buzz cannot always lie if he tells the truth about always lying). Thus, given one of these statements was indicated to have been correct, it must be Apollo’s.

Bee-tween the trains logic puzzle

Two trains, 200 miles apart, are heading towards each other. Both trains are going at a speed of 100 miles per hour. A little bee starts flying from one train towards the other. The bee is flying at an amazing speed of 150 miles per hour! When the bee reaches the other train, it turns around and flies back to the first train. It keeps going back and forth between the two trains until they crash into each other! Thankfully, the people on the trains and the little bee are unharmed.

In total, how far did the little bee fly between the two trains before they crashed?

Reveal solution

Finding the solution to this puzzle is simpler than it first appears. Since the trains are both travelling 100 miles per hour towards each other, their relative speed is 200 miles per hour. It will therefore take one hour to cover the 200 mile distance between them. During this one hour, the little bee will have travelled 150 miles.
