We all know some crayon colors are more popular than others, so what can you do with all the leftover little pieces? You can melt them down and make *new* crayons. As this page on instructables.com shows, if you toss the stubs in a mini-muffin tin and bake them at just 275 degrees, they’ll melt and mix, giving you swirly, tie-dyed crayon chunks. The edges are sharp enough to draw thin lines, and if you want to switch to a different color, just flip the muffin over in your hand!

*Wee ones:* If you have red, orange, yellow, green and blue crayons, how many colors do you have?

*Little kids:* What colors do you see in the tie-dye crayon in the bottom right corner? Point to it! *Bonus:* If you use 3 new colors in each tin, how many colors will 3 muffin crayons use?

*Big kids:* The crayon muffins take up to 13 minutes to bake. If you start at 3:45 pm and bake them for 13 minutes, when do they finish? *Bonus:* If you need 8 pieces in each muffin cup, what’s the greatest number of complete crayon muffins you can make with 50 pieces?

*The sky’s the limit:* If you have blue, red, and purple crayon pieces, and in your 24-muffin tin you put blue in 1/2 of the cups, red in 1/3 of them, and purple in 1/4 of them, what’s the smallest number of crayon muffins that have to hold at least 2 different colors?

__Answers:__

*Wee ones:* 5 colors.

*Little kids:* Mostly red, with 2 shades of green. *Bonus:* 9 colors.

*Big kids:* At 3:58 pm. *Bonus:* 6 crayon muffins: they will use 48 pieces, leaving 2 leftovers.

*The sky’s the limit:* 2 crayon muffins. The blue will go into 12 of the cups, and red can go into 8 of the other 12 cups. That leaves just 4 empty cups, but purple has to fill 6 cups, so there will be 2 that have to pair purple with either red or blue.
