Picture of Popping Chocolates
These innocent looking treats have a trick inside them. Give them to your trick-or-treaters and watch as the discover the popping trick inside.

You will need:
Chocolate - Whatever kind you prefer, I used dark chocolate because that is what I had
Pop Rocks
Silicon ice cube tray - I got mine at Dollar Tree

Step 1: Melt the chocolate

Chop the chocolate into small pieces, this will help it melt easily without burning

Melt however you would like, I used the microwave stirring it every 20 seconds
Clever idea - being a Doctor Who fan I think the pop rocks would also suit a TARDIS mold very well.
yumm... OWWWW!
