I saw this on pinterest a year or two ago, and thought they were super cute!
The original poster, did not use marshmallows, but I thought they gave it a little extra something special. My daughter sure had a hard time keeping her grubby paws off all the candy as I assembled the bags, so instead of one bag of rainbow twizzlers making 5 rainbow treat bags (which I thought was a lot!) It only made 4.
To make yourself -
You'll Need:
1 bag of Rainbow Twizzlers
1 bag of Rolo's
1 bag of mini marshmallow's
sandwich or cellophane bags
To assemble, place each of your rainbow pieces in the correct order. Red, Orange, Yellow, Green, Blue, Purple. Open your baggie and add in your rolo pieces. I used 4 (for 4 leaf clover).
Then pick up all your rainbows pieces and slide them in one side of the bag, then bend, to shape into a rainbow and place on the opposite side of the bag so that the rolo's are in the middle.
For the "clouds" I used 6 marshmallow pieces for each side. You have to kind of tuck them in so they're not rolling around. That's it.
BTW, These do not travel well. If you're making them for a classroom, I would definitely use the cellophane bags over sandwich bags, as they're smaller and would create a more compact rainbow. These were for my daughters cousin's, so luckily they weren't too hard on us. Like most kids, I think they were just excited to be receiving CANDY! ;)
