5 oz hard cups with shot glasses added for Valentine’s Day
Hard cup sparkleballs require a bit more effort. They take 3 days to make, so glue can set. The cups crack easily, and if you drop a hard cup sparkleball, it’s a disaster. But hard cups are sparklier, and they come in fun colors. Instructions will work for 5 oz cups and Party Essentials 9 oz. For 9 oz Chinet brand cups the formula is slightly different. (see below)
64 hard solo-style cups
large paper clips
gluegun & soldering iron
5oz 14-11-6-1 / 64
9oz Party Essentials 14-11-6-1 / 64
9oz Chinet 14-11-6-1 + middle row of 14 / 78
Clip 14 cups in a ring.
If 14 doesn’t make a nice tidy circle, your cups aren’t right.
Switch to Any Size Cups instructions.
Clip 11 cups in a ring. Then clip it on top of 14-cup ring.
Clip 6 cups in a ring. Add 1 cup in the center.
Clip this on top of 11-cup ring to complete one side.
Build 2nd side the same way.
Where cups touch, remove clip and add dab of hot glue.
Instead of glue you can use silicon caulk.
Let glue harden overnight for tight bond.
DAY 2: melt 1/2″ hole in each cup bottom with soldering iron.
M ust be done outside in good ventilation.
Start lights at plug end. Insert 2 in cup on outside edge.
Work cup by cup, into center and back out, all the way around .
End at cup next to one you started with. More detail.
On 2nd side, start lights from opposite end of cord and insert the same way.
If you have extra lights stuff them into the middle or add to random cups.
Clip 2 sides together.
Hot glue where cups touch.
Let set overnight.
DAY 3: Melt hole between two cups and add a hanger.
I used a zip-tie and metal ring here.
Plug in and enjoy!
Hard cup sparkleballs by Carl Boro, who taught me his technique. Carl prefers clear silicon caulk instead of hot glue. The caulk takes several days to set. He also uses a |14-11-6-1 + 14 in the middle| formula with Chinet cups.
