Here's what you need:
Karo Syrup {Light}
Red Food Coloring
Glasses/Cups {any kind will do, but clear cups work the best for blood effects}
*Pour your Karo Syrup into a shallow bowl. I never measure my syrup, I just guess with how much I want to use. It always depends on how many cups you're planning on doing. Add your red food coloring to the syrup and stir. I don't measure my food coloring either. It depends on how "red" you want your blood to be, so again, it's completely up to you on what you want it to look like.
*Dip the rim of your glass/cup into the red syrup. Pull your cup straight up and then flip it over and set it down.
*Over the next few seconds your "blood" should be easily dripping down the sides of your glass/cup. Creepy. Scary. Cool. If you're not planning on using your blood cups right away, immediately place them in the freezer for a few minutes. This will help prevent the blood from going all the way down the cup. You don't want your kids grabbing a cup and have yummy sticky red hands. Like I said, this can get a little messy with the little one's.
*If you are planning on doing a ton of cups {like for a party or something}, you'll have to do the "freezing" part in shifts. Do a couple of cups, then instantly place them in the freezer. While they are cooling and the syrup is hardening, do your next set of cups. Then swap them. Now, don't freezer them for too long. You'll only want them in there for 20 minutes or so, just to stop the dripping process. If your not planning on using them for several hours, place them in the fridge after your done freezing your syrup. It will still keep the blood from sliding down further on the glass and the blood will still be soft, but not hard.
TIP: I love the fact that this fun Halloween trick is completely safe and non-toxic. Your kids will have a blast drinking "blood". I also suggest using clear plastic cups for the kids. Have a fun filled Halloween and please be safe.
