Attach blown up balloons to skewers with tape. Grease each balloon with oil. This is optional, because it usually comes off without oil. If you’d like to play safe, grease them.
Add water and gelatin to a microwave safe bowl. Mix until well combined. Allow it to bloom (rest) for 10 minute Place in microwave for 15 seconds, or until it is dissolved. Add gel paste at this point.
Dip balloons into the gelatin mixture, leaving the tied end wear the balloon meets the stick without gelatin.
Place the coated balloons on a piece of styrofoam and allow to dry for about 24-48 hours.
To remove balloon, cut a small slit by the knot and gently pull the balloon out from the bubble. You can trim the base, where the hole is, so that it lays evenly onto the cake.
