In a statement on Wednesday, Kim Yo Jong, the powerful sister of North Korean leader Kim Jong Un, confirmed that the North sent the balloons to make good on her country’s recent threat to “scatter mounds of wastepaper and filth” in South Korea in response to leafleting campaigns by South Korean activists.

She said they were deployed to make good on her country’s recent threat to “scatter mounds of wastepaper and filth” in South Korea in response to the leafleting campaigns by South Korean activists.

"Mounds of wastepaper and filth will soon be scattered over the border areas and the interior of the ROK and it will directly experience how much effort is required to remove them," said North Korea's vice-minister of defence Kim Kang Il said in a statement to state media on Sunday.

The team then created a heavy-duty version of their wastepaper foam by combining the pulp, gelatin, PVA glue, and a silica-based fluid that hardens as force is applied.

Among the many kinds of trash that accumulate within a home, wastepaper is one of the most common.
